    Effektivisera materialflödet med hjälp av självgående truckar2015Independent thesis Basic level (degree of Bachelor), 180 HE creditsStudent thesis
    Abstract [en]

    The thesis that follows is performed in collaboration with Nitator in Oskarström.The factory in Oskarström focuses on laser cutting, robotic welding and surfacetreatment of steel for the automotive industry.

    The project aims to streamline the flow of materials in production by automatingthe movements of the forklifts, running to and from the interlayer, and betweenworkstations.

    The project started with a systematic literature search. The literature searchshowed the research position around the AGV-system. Also a review of studentliterature was made, so that a suitable method for practical implementation couldbe developed and applied. Selected method uses both quantitative and qualitativeapproaches, which is analyzed by using triangulation.

    The work has resulted in a modified layout of the current facility in Oskarströmthat can be used for the implementation of the AGV-system. It has also resulted inthe tender documents and profitability calculation from several of AGV-suppliers.

    Analysis and evaluation of the ergonomic simulation software IMMA2014Independent thesis Advanced level (degree of Master (One Year)), 10 credits / 15 HE creditsStudent thesis
    Abstract [en]

    This thesis is the final project for the author’s master’s studies at Halmstad University. It has been completed within a research project (CROMM) at the University of Skövde.

    The purpose of the thesis was to analyse and evaluate if the ergonomic simulation software IMMA can be used to support design and evaluation of vehicle design. Four thesis questions were addressed. The objectives were to obtain a demonstrator that shows what the IMMA software can be used for, and to receive initial design data for design of ergonomic car trunks.

    Semi-structured interviews have been held with people who work with vehicle ergonomics at Volvo Cars, Scania and AB Volvo, and needs were identified within the following fields:  position, motion, envelopes, integration, evaluation, visualisation and general needs. An analysis of the results and the IMMA software was performed. The conclusion was that IMMA supports the basic needs for design and evaluation of vehicle ergonomics and therefore needs further development, both modifications and new functions.

    A method from the HFES 300 Committee was used for evaluation of the trunks together with simulations in IMMA. The result showed a variation depending on where in the trunk the box is placed. The analyse lead to the conclusion that the results cannot be seen as fully repeatable or reliable. A new function is needed in order to make it possible to fully evaluate the result.

    The recommendations are to start with development of the sit-positioning and an evaluation module. Although, the development of how to make the tool more time-efficient, user-friendly, repeatable and reliable, must be taken into consideration in each development step.

    Symbolic Characterisation of Commonalities in Testing Software Product Lines2016In: 2016 9TH IEEE INTERNATIONAL CONFERENCE ON SOFTWARE TESTING, VERIFICATION AND VALIDATION (ICST), Piscataway, N.J.: IEEE , 2016, p. 387-388Conference paper (Refereed)
    Abstract [en]

    Validation and verification of Software Product Lines is particularly challenging due to the complex structure and interaction of commonalities and variabilities among products. There are several approaches to specify the structure of such commonalities and variabilities, such as the delta-oriented approach. Building upon such a structure, we propose an approach to avoid redundant analysis in Software Product Lines by extending them to semantic behavioural changes. To this end, we propose to use Differential Symbolic Execution, an automated technique for proving functional behavioural equivalence based on satisfiability modulo theories. Our proposal aims at identifying the behavioural commonalities of one software product relative to another and exploits them in order to establish an efficient model-based testing trajectory.

    Abstract [en]

    The aim of this thesis has been to develop a proposition for a new type of snail barrier, whose function is not based on the use of toxic chemicals or electric current. We have mainly used Fredy Olsson´s methods described in the compendium "Princip- och primärkonstruktion" After a thorough review of previous research and the accompanying definition of criteria, we sketched out six different propositions. By weighting the criteria in a Kesselring matrix, we selected one of the proposals for further development. The main criteria we had to take into account were; the weight of the product, the ability to recycle the material, the price and that it would be modular. The work has resulted in the development of a product that meets all the criteria, and is ready for manufacturing, though field conditions tests that can confirm the effectiveness remains to be done.

    Framtagning och utveckling av ett stapelbart träningsredskap för olympiska lyft samt gym och fitness2019Independent thesis Basic level (university diploma), 10 credits / 15 HE creditsStudent thesis
    Abstract [en]

    The goal of the project was to design a product that Eleiko lack in their assortment, stackable jerk blocks for training of olympic weightlifting and also for gym and fitness. The goal was achieved using Fredy Olssons primary- and principle-contruction method mixed with Eleikos own working methods. The practical work began with a couple of smaller brainstorming periods followed up with basic assessments. A lot of the steps in Fredy Olssons method had to be repeated to produce our results. Different types of wood specimens have been researched as well as the possibility to use a sandwich construction. Experiments have been done to understand the bounce and fatigue of different materials. All the requirements have been achieved with a unique design inspired by anthopometry. This has led to two main advantages compared to competitors, namely the reduced weight and the height adjustments. A physical prototype has been manufactured and will be carefully evaluated by Eleiko after our project has ended, before it can be released to the market.

    This thesis is in line with the two author’s orientation within the mechanicalengineering program. The orientation is production development and the project hasbeen to develop a new packaging line based on a simple existing one. The existingsystem is located in a dairy plant and have old equipment and low capacity which theplant want to improve.

    The project has given the authors opportunity to use andwiden their knowledge within their area of education.The project includes a lot of research, the theory behind the project is amongst otherthings; production systems, evaluation systems, work ergonomics, models forproduction development, directives, rules and data for the machines and equipmentneeded for the project. Contact has been made with several machine suppliers to findinformation and to get prices.

    The method used was decided during the projects background study, the method isdeveloped by Bellgran & Säften (2005) and is a method designed purely forproduction development. Only applicable parts of the method has been used whichmeans that some parts where left out such as the part for deployment since theproject won’t be realized as of now. The method included a study of the currentsystem and similar production systems as well as interviews with the staff.

    This project has led to a number of concepts for a new production system that worksvery different compared to the old system. The authors are very pleased with theresulting new final concept and the improvements it lead to which is technical andeconomical. The main results is 50% improved capacity and reduced heavy manualtasks which has resulted in less need of line operators.

    Implementation of usability analysis to detect problems in the management of kitesurfing equipment2011In: Procedia Engineering, ISSN 1877-7058, E-ISSN 1877-7058, Vol. 13, p. 525-530Article in journal (Refereed)
    Abstract [en]

    Equipment used for high-risk sports, such as kitesurfing, needs to be efficient for the intended use and the user, and thus meet the mechanical demands and provide sufficient safety. Accidents related to kitesurfing occur, and the consequences are sometimes catastrophic. One important factor is the equipment design, which can influence the type and number of injuries due to insufficient safety systems. The aim of this study was to investigate how the design of kitesurfing equipment can affect safety issues from a usability perspective in relation to the task of preparation. A focus group of 6 subjects analyzed the task of preparing kitesurfing equipment for riding, using the evaluation methods Enhanced Cognitive Walkthrough (ECW) and Predictive Use Error Analysis (PUEA). From the evaluation, a list of plausible usability problems was identified together with proposed design guidelines. The results showed that usability problems occur during preparation. In total 35 usability problems were found, of which 11 (4 from ECW and 7 from PUEA) have a great impact on safety. These 11 problems were hard to detect for the user and could result in serious consequences for the kitesurfers during rideing. The analysis resulted in some general guidelines that are possible to implement on different types of kites. To conclude, education and improved design of the equipment are essential to increase the safety of the sport.

    Comfort aspects important for the performance and safety of kitesurfing2012In: Work: A journal of Prevention, Assesment and rehabilitation, ISSN 1051-9815, E-ISSN 1875-9270, Vol. 41, no Suppl. 1, p. 1221-1225Article in journal (Refereed)
    Abstract [en]

    Equipment used in sports is of great importance, especially when the equipment is in direct contact with the athlete or is important for safety. In the sport kitesurfing environmental factors and the equipment design are crucial for the comfort and safety. The participants’ choice and opinion of equipment can show which factors are considered most important for the performance and to reduce risk for injury. This study has evaluated self-reported information from the participants about what equipment they use, comfort of the equipment and if the equipment has contributed to any injuries. The methods used were questionnaires (n=206) and interviews (n=17), which in combination allows to assess the problem both quantitatively and qualitatively. The results showed that supported leading edge kites are most frequently used, with a waist harness and foot straps to attach the feet. The choice of kite type was mainly based on the discipline of riding for the respondent. Some issues concerning comfort of riding and injury risk the respondents did relate to the design of harness and foot straps. The information from this study can be used for development strategies for industry manufacturers and for further studies in the area of equipment design and biomechanics. © 2012 - IOS Press and the authors.

    Normalizing stance width2012In: Neuroplasticity, Motor control, Cutting-Edge Technology & Rehabilitation: Proceedings of the XIXth Congress of the International Society of Electrophysiology & Kinesiology / [ed] Kylie Tucker, Bianca Butler and Paul W Hodges, Brisbane: NHMRC Centre of Clinical Research Excellence in Spinal Pain, Injury and Health , 2012, p. 221-221Conference paper (Refereed)
    Abstract [en]

    INTRODUCTION: In previous studies, stance widths are most often determined as a percentage of shoulder width, where 70% of shoulder width is considered a narrow stance width and 140% of shoulder width is considered a wide stance width. A few studies have also normalized stance width to the width of the hips (distance between trochanters). However, there are also a possibility to normalize stance width in relation to the length of the lower extremities, since this variable might not change as much in dynamic situations and may correlate higher to the angle of the lower extremity in a frontal plane. AIM: This study aims to compare measurements of stance width when normalized to shoulder width, hip width and leg length for three different stance widths with feet attached to a board. METHOD: Motion capture (Qualisys, 16 Oqus-cameras) was used to measure 7 active male kitesurfers with their feet attached to a kiteboard (136 cm). They were 20-28 years old, in average 180 cm (SD=7 cm) and 78 kg (SD=7 kg). The subjects were standing with three different stance widths, using the same external rotation (20° bilaterally). Markers were attached to shoulders (acromion processes), knee joint lines, hips (trochanter major), heels (mid-posterior of calcaneus) and ankles (lateral and medial malleoli). Stance width was measured as the distance between the two medial ankle markers and normalized towards the distances between (1) the shoulder markers, (2) the hip markers and knee marker plus knee marker and lateral ankle marker and (3) the right and left hip marker. Furthermore, the angle of an extended lower extremity towards a vertical line in the frontal plane was measured. All measurements were done twice, and SPSS 20 was used for data analysis of correlation (Pearson’s r). RESULTS: The measured stance widths between ankles were 39.9 cm, 43.6 cm, and 48 cm (SD=1.2-1.4) for all subjects. The correlations (r) between the angle of the leg towards a vertical line and normalized stance width for the three normalization variables were: (1) 0.79, (2) 0.96 and (3) 0.93. All of the correlations were significant at a level of p>0.01. CONCLUSION: The results show that the variables hip or leg length would be preferred to use when normalizing stance width for young male athletes, standing in wide stance widths. Further studies using a greater number of subjects, more stance widths and a more heterogeneous group are suggested for the future.

    IMPROVED DESIGN FOR HYDRAULIC VALVE AND HYDRAULIC VALVE TESTING RIGIMPROVED DESIGN FOR HYDRAULIC VALVEAND HYDRAULIC VALVE TESTING RIG: DESIGN AND PRODUCT DEVELOPMENT2014Independent thesis Advanced level (degree of Master (One Year)), 40 credits / 60 HE creditsStudent thesis
    Abstract [en]

    The hydraulic testing rig is a machine that is used to test the hydraulic valves.The present testing rigs are used according to only some particular specification, but in ourproject we have developed a process and implemented the idea for building a UniversalHydraulic Testing Rig which can be able to test any kind of valves with simple adjustments.The hydraulic valves are mainly designed to carry out the flow of the hydraulic fluid with thedesired pressures. But it is observed that there are many pressure losses in the flow whichleads to the unreached flow pressures as expected. In a pre-project to this work a patentedhydraulic valve designed to improve the flow pressure of the hydraulic fluid. The main targetof the design of the valve is to decrease pressure losses and give maximum output from theother end of the valve. The Hydraulic Testing Rig is designed with the help of design softwareand flow simulation process helps to know about the pressure flow from inlet to outlet ofthe valve. After the testing of the design, the valve is tested on the new universal hydraulictest rig developed in this project. With the future use of the hydraulic valve test rig, thesimilarities and variations are observed from both the simulations done and test results canbe compared to optimize the valve design further. With the combination of hydraulic test rigand redesign hydraulic valve we will provide and experimental test rig possibility to bringthe better and maximum design that could be attained reducing the energy losses in hydraulicvalve designs.

    Simulation of Removal Functions for Abrasive Grinding Tool: Numerical Simulation Of Tool Influence Function2016Independent thesis Advanced level (degree of Master (One Year)), 10 credits / 15 HE creditsStudent thesis
    Abstract [en]

    A relatively large set of complex data can be described using a simple mathematical Prestonequation. However the parameter choices are an essential facet that determines the efficiencyof grinding. The depth and volume of removal contributes to a significant part of the grindingoperation that accounts for the manufacturing time. These interacting factors in the equationare studied to create, infer and compare the performance of three sets of grinding tools: padtool, brush tool and radial tool. The tools are generated using MATLAB and is provided as aninput for tool path generation. The geometry profiled by the tool influence function is generatedusing Preston equation and the analysis from the simulation shows that the pad tool can bepreferred in instances where maximum removal is required. The comparison amongst the toolswas made keeping the parameters (pressure and relative velocity) constant in the equation forthe different tools.

    Abstract [en]

    In the recent past there has been a step change in manufacturing strategies and technologies primarily as a result of globalisation and extreme pressure on increasing competitiveness. To be competitive and maintain profit in such a dynamic environment, a manufacturing enterprise must be capable of adjusting quickly to the market. This has lead to the emergence of a new manufacturing strategies such as agile manufacturing, where multiple companies co-operate under flexible virtual enterprise structures. The main purpose of AM is to obtain high quality, shortest lead- time, good service at the lowest cost to satisfy customers' requirements. To respond to the market rapidly, companies have to work closely with their suppliers, customers, and partners to shorten the product development lifecycle and to highlight potential problems. Simultaneous requirements of high quality and rapid co-operative business demands effective information and data handling systems. Specifying surface texture for products will have a heavy impact on the cost and function of the final product and consequently becomes a critical factor in AM based product specification.

    Automation of coolant agent extraction in refrigerators2019Independent thesis Advanced level (degree of Master (One Year)), 40 credits / 60 HE creditsStudent thesis
    Abstract [en]

    Refrigerators contains something called CFC which is a gas that depletes the ozone layer if it is not handled correctly. The recycling of refrigerators has therefore a lot of regulations surrounding it, making it extremely important to have full control over the recycling process.

    The pre- treatment process of refrigerator recycling is today a fully manual process. This introduces high amounts of physical strain on the employees, especially in the compressor removal stage. This project focused therefor on developing conceptual ideas for automating or semi-automating the pre-treatment process at the Stena Nordic Recycling Hub in Halmstad, Sweden. Since there are no automated pre-treatment manufacturing lines in the recycling industry today regarding refrigerators, a theoretical review on related areas was done. Visits to the plant were made and employees were interviewed about the current process.

    In the end two concepts were presented as suitable ideas for automating the process to an extent that removes the major physical strain of the production line but still contains the control of the process. One concept for the stage of removing the compressor and one concept for the production line as a whole. The compressor removal concept utilizes an articulated robot equipped with a claw that is controlled by an image analysis system.

    Handlingsutrymme: Vilka faktorer ökar och begränsar en anställds handlingsutrymme2013Independent thesis Basic level (degree of Bachelor), 10 credits / 15 HE creditsStudent thesis
    Abstract [sv]

    Handlingsutrymme är en möjlighet för en arbetare att själv styra sina beslut, inom verksamhetens givna ramar. Handlingsutrymme kan delas in i två delar, objektivt och subjektivt handlingsutrymme. Det objektiva handlingsutrymmet är det handlingsutrymme som tilldelats av verksamheten, och finns inom dess riktlinjer och ramar, medan subjektivt handlingsutrymme är det som den anställde tror sig ha. Forskningen kring handlingsutrymme har i dagsläget vissa kunskapsluckor, och vår studie syftar till att få klarhet i vilka faktorer som ökar och begränsar handlingsutrymmet en anställd har vid sin arbetsplats.

    För att besvara vår problemformulering har vi genomfört fem intervjuer med anställda inom den sociala sektorn. Vår teoretiska del bygger till stor del på fakta från böcker samt forskares studier och undersökningar. Resultatet visar att många faktorers inverkan på handlingsutrymme inte belysts särskilt väl i den tidigare forskning som finns, och att en helhetsbild är viktig för att kunna utläsa vilka faktorer som ökar och begränsar handlingsutrymmet.

    Awning Arm Folding Mechanism: FA-40 Series2016Independent thesis Advanced level (degree of Master (One Year)), 10 credits / 15 HE creditsStudent thesis
    Abstract [en]

    The necessity to change the mechanism of the arm folding is to make a major

    difference in the field of Sun roofing systems and also to reduce the cost of the

    Awning system. The reduction of cost may help the market of the awning system to

    reach the Upper- Middle Class customers.

    In this project various technical solutions were investigated by simulation

    softwares and the data was taken into consideration. The best solution has been

    processed and investigated in depth with cost and material cost with high

    preference which cannot be exceeded when compared to today’s Awning arm

    folding solution.

    The best solution for replacing today’s mechanism is a torsion spring folding

    mechanism. The torsion spring has been designed and simulated using the

    SolidWorks simulation software. A virtual bench test of the Awning system has

    been created and designed using SolidWorks and the working mechanism has

    been tested virtually.

    The torsion spring’s data was calculated by using a spring dimension calculator.

    The spring data has been included in the bench test and the test simulation has

    been run by a virtual technique and then the result has been obtained by the

    virtual test bench.

    The torsion spring’s stress and strain analysis during maximum load on the

    Awning in an open condition has also been calculated for the study purpose of the

    spring stability and compared with the previous method of the awning system in

    order to calculate the factor of safety (FOS) equal or more stabilise for the

    environment as it has been used.

    The environmental condition is a main focus in this project. There are different

    types of weather conditions in Sweden. Customers may use the Awning during

    rainy weather. While it is raining the rain water are collected on top of the fabric.

    In order to withstand the weight of the water the arm of the awning should be

    strong. Hence the environmental condition is a main factor in this project with

    respective to speed of the wind.

    The economical manufacturing cost for the product and the replacement of the

    arm folding mechanism are mainly focused.

    Betydelsen av personalens engagemang för att arbeta med arbetsmiljöarbete: -med utgångspunkt ifrån fyra engagemangskapande faktorer2015Independent thesis Basic level (degree of Bachelor), 10 credits / 15 HE creditsStudent thesis
    Abstract [en]

    The purpose is to increase awareness of the importance of staff engagement in the work environment and how the organization works to engage employees to want to participate actively in the work environment.

    The questions we seek answers to in this study is the following:

    • What affects the staff to engage in the work environment from a management

      perspective

    • Are there external factors that affect the organization and the individual's engagement

      to work with the working environment?

      We have create a model that is based on recent research to define our definition of engagement. The model contains four factors : Clarity, Advocacy opportunities, resources and feedback. The method we have used to answer the purpose in this study is ten qualitative interviews with persons with work environment responsibilities.

      The result shows that the engagement regarding work environment is important to get the employees to actively participate. To get the engagement from the employees the organizations need to provide, clarrity, advocacy opportunities, resources and give mutual feedback. External factors such as high and low season affect the organization's work environment, but not the individual engagement regarding work environment.

    Taktningsutrustning till Ljungbymaskin2017Independent thesis Basic level (degree of Bachelor), 10 credits / 15 HE creditsStudent thesis
    Abstract [en]

    This bachelor thesis was made on behalf from the wheel load maker Ljungby Maskin AB. Ljungby Maskin is right now in an expansive stage with a development of the welding workshop and the paint shop. In relationship to this they are also changing from station assembly to production line. Because of the progress they have needs of some type of transport method. The first step of the project was to decide what method that should be used. Rune Andersson, one of the supervisors in the project was at first into using air caster/air bearings to transport the production. However after some research the result was that air caster wasn’t the best method to use.  To make this conclusion a visit at Atlas Copco was made to see their production lines and a discussion with the production developer at AC was made. After the method was decided, the design of the fixtures could be made. The method to make the design was principle and primary design by Fredy Olsson. The output from this gave in total 12 different constructions. Pugh-matrix was made at the different constructions to be sure which one that should be used.  Complete CAD-models were made for the constructions that got the highest mark. Through a product draft it was determined which details that should been bought and which should be self-designed. Complete detail constructions were made at these parts. To ensure the strength of the parts, FEM-analysis was made in CATIA V5. The conclusion was that the project will be a good support in the development of the new assembly workshop at Ljungby Maskin AB and that it will contribute to a smaller storage and increase the production.

    Redesign of needle positioning system for breast biopsy: Cytoguide, the world's first fully automated positioning intrument for breast biopsy2019Independent thesis Advanced level (degree of Master (One Year)), 10 credits / 15 HE creditsStudent thesis
    Abstract [en]

    This thesis document is a detailed description of the redesign of a breast biopsy needlepositioning system. It describes the current machine and its problem, an outdated drivingsystem, as well as giving a general understanding of taking a breast biopsy. Thisto clarify the topic to the reader and giving them a better understanding and to designa more complete product. This introduction was followed up by a research part aboutcontemporary driving and guiding systems. By the use of a morphology and decisionmatrix as well as a meeting with the company it was soon decided that linear guiderails in combination with a special type of stepper motors was the best solution forthe problem. After this decision was made, the project continued by making a detailedCAD model. The biggest challenge here was making the machine as compact as possible.With the design choices made, the result is a machine which is as compact as it canget. The last stage of the project was doing a verification. This was already partly donein deciding which stepper motors and linear guide rails were suitable. However, checkingif the machine would be able to handle the forces specified in the list of demandsand wishes still had to be done and is executed with the use of FEM. After the FEManalysis was executed it was soon concluded that the stress limit of the aluminum alloywas not reached and the maximum deflection was below the limit. A few demands wereleft untested because it would require a prototype made of its actual components andmaterials used for the production machines.

    Towards robust polishing strategies for moulds and dies2009In: Proceedings of the 3rd Swedish Production Symposium, Göteborg, Sweden, 2-3 December 2009 (SPS09), Swedish Production Academy , 2009Conference paper (Refereed)
    Abstract [en]

    This paper summarises several experiments performed in order to increase the knowledge about the polishing process (e.g. to better understand the origins of different defect structures) and to develop new polishing strategies for dies and moulds with high demands on surface quality, i.e. glossy and ‘defect free’ surfaces. The polishing strategies are not only a help to avoid unwanted surface structures, they will also work as the base for automated polishing systems, which have several advantages compared to manual polishing; vibrating hand tools and monotonic work can be avoided, dust and noise levels as well as total process time can be reduced, and more consistent surface finishes from tool to tool can be achieved.

    A selection of steel samples, polished with different techniques, were analysed to study how the final surface quality was influenced by e.g. the process route, the degree of purity and the microstructure. The surface quality was here represented by roughness values and SEM-images. It could be concluded that the degree of homogeneity and the purity level of the steel materials were crucial to final surface qualities; the lower amount of inclusions, the better the surface quality. Further, a classification of occurred defect structures made.

    Friction in Sheet Metal Forming: A Comparison Between Milled and Manually Polished Die Surfaces2010Conference paper (Refereed)
    Abstract [en]

    The evolvement of product requirements in the automotive industry, e.g. reduced weight, means that the use of advanced high strength steels (HSS, EHSS,UHSS) in automotive applications is continuously increasing. The introduction of high strength steels in production implies increased tool wear and calls for functional tool surfaces that are durable in these severe tribological conditions. In this study the influence of tool surface topography on friction has been investigated. The frictional response was studied in a Bending Under Tension test. The results did show that a low frictional response was generated by low slope of roughness profiles combined with a strong anisotropy applied perpendicularly to the sliding direction. An improved machining strategy has a high potential to significantly reduce the need for manually polished surfaces.

    Uncertainties and optimized sampling in surface roughness characterization2011In: Wear, ISSN 0043-1648, E-ISSN 1873-2577, Vol. 271, no 3-4, p. 610-615Article in journal (Refereed)
    Abstract [en]

    Usage of 3D roughness parameters measurements requires knowledge of uncertainty causes in order to design proper measurement procedures. Even on apparently homogeneous machined surfaces, large local variations in 3D roughness parameters have previously been reported. This paper introduces and tests a concept for optimized sampling based on local-, and global topography analysis, using measurements of the Sa parameter on a large machined component as a practical example. It is shown that more than 40 measurements of Sa may be needed to attain a stable value, but that choice of an appropriate sampling strategy may reduce this requirement considerably. The results point to a possible route to minimize required measurements and contribute to the development of the "best-practice" when using 3D surface structure metrology.

    Machine Hammer Peening: A Substitute for Polishing of Pressing Die Surfaces?2009In: Proceedings of the 3rd Swedish Production Symposium, 2009, p. 184-189Conference paper (Refereed)
    Abstract [en]

    Machine hammer peening (MHP) is a new method for finishing of surfaces. With this method, the workpiecesurface is hammered with a spherical carbide tool. The mainobjective of the study was to evaluate whether the MHPmethod could become a plausible substitute for manualpolishing in pressing die manufacturing where nodular castiron is a common workpiece material. To do this, samplenodular cast iron surfaces were hammered and evaluated. Changes to the surfaces were evaluated using surfaceroughness measurements, hardness measurements and opticalimages. First of all, the workpiece surface was smoothened. Secondly, the surface hardness was increased significantly. Thirdly, the nodules on the workpiece surface wereaffected. They appeared to be smaller and not as visible. This effect would likely create a die surface less prone to gallingsince the cavities would not be filled with sheet metal to thesame extent in a forming operation. In addition, withMHP, theamount of polishing needed to manufacture a die surface canbe reduced because of the smoothening effect.

    Kansei, surfaces and perception engineering2016In: Surface Topography: Metrology and Properties, ISSN 2051-672X, Vol. 4, no 3, article id 033001Article in journal (Refereed)
    Abstract [en]

    The aesthetic and pleasing properties of a product are important and add significantly to the meaning and relevance of a product. Customer sensation and perception are largely about psychological factors. There has been a strong industrial and academic need and interest for methods and tools to quantify and link product properties to the human response but a lack of studies of the impact of surfaces. In this study, affective surface engineering is used to illustrate and model the link between customer expectations and perception to controllable product surface properties. The results highlight the use of the soft metrology concept for linking physical and human factors contributing to the perception of products. Examples of surface applications of the Kansei methodology are presented from sauna bath, health care, architectural and hygiene tissue application areas to illustrate, discuss and confirm the strength of the methodology. In the conclusions of the study, future research in soft metrology is proposed to allow understanding and modelling of product perception and sensations in combination with a development of the Kansei surface engineering methodology and software tools.

    Outsourcing and knowledge integration in new product development2009Doctoral thesis, comprehensive summary (Other academic)
    Abstract [en]

    This thesis deals with two aspects of knowledge needed for new product development; theaccess to external knowledge through outsourcing of NPD and the integration of knowledgedeveloped when outsourcing activities in the NPD process. As modern products competing onincreasingly international markets call for both complex and specialized knowledge, it isbecoming more important to take an outward perspective of knowledge, searching for externalknowledge sources, in order to be competitive. But it is also important for the firm to take aninward perspective on integration of the knowledge achieved from external sources in order tosecure the knowledge gained.

    Outsourcing of New Product Development (NPD) refers to the outsourcing of activities fordeveloping new products (goods and/or service), where all or the innovative part of the NPDprocess is purchased externally according to a contract from organizational units separatefrom the outsourcing firm. This means that the service to develop a whole or a part of a newproduct is outsourced. This definition implies that (A) the outsourced activity shall be aninnovative (strongly contributing to the newness) part of the NPD process, (B) the outsourcedactivity was previously conducted internally, and (C) the activity shall be purchased andregulated in a contractual agreement between the organizations.

    Knowledge integration refers to the process of acquiring, sharing, and making use ofknowledge by combining it with previous knowledge in order to create new value. Becauseknowledge possessed in collaborating firms is often complementary, it is important tocombine it with previous knowledge in the firm. Therefore knowledge integration is chosenthroughout the thesis as the term for the overall process.

    Based on transaction costs theory, resource based and knowledge based perspectives twomajor issues are investigated. First, the identification of which factors are the most importantfor firms when making the decision to outsource activities in the NPD process. Second, theestablishment of the importance for knowledge integration of external knowledge in the firm,and to find what role level of involvement among staff plays for efficiently achievingknowledge integration.

    The thesis is a compilation thesis (with six appended papers) based on findings from threequantitative studies and a longitudinal case study (presented in two of the appended papers).Using cases from and samples of medium-sized manufacturing firms with in-house NPD itwas found that, while cost has been traditionally considered the most important factor foroutsourcing in general, search for external knowledge is found to have a greater importancewhen intangible processes as NPD is object for outsourcing. It is also found that thematicknowledge is the most important type of knowledge to efficiently integrate to achieve highinnovation performance and that a higher degree of processes and culture supportinginvolvement, increase knowledge integration when outsourcing activities in the NPD process.

    Easy Click: Det lättmonterade glashuset2010Independent thesis Basic level (degree of Bachelor), 15 credits / 22,5 HE creditsStudent thesis
    Abstract [en]

    An overwhelming difficulty lies in the assembly of greenhouses. This has shown to be a time consuming and complex process. The assembly instructions are often insignificant and the process of assembling a greenhouse can take up to two days. This degree project has focused on the shaping and assembly of the aluminum profiles that are used in greenhouses. The result is Easy Click, the easy built glasshouse.

    Easy Click is a glasshouse completely without screws. Instead, the assembly uses smart tracks and bonds that have been integrated into the profiles. This means, among other things, that no screw holes are required, thereby making the profiles very easy to manufacture. The glasshouse is easy to assemble as well as exclusive and easy to manufacture.

    Traceology, quantifying finishing machining and function: A tool and wear mark characterisation study2011In: Wear, ISSN 0043-1648, E-ISSN 1873-2577, Vol. 271, no 3-4, p. 553-558Article in journal (Refereed)
    Abstract [en]

    Traceology is defined as the study of wear marks and its history in criminology and archaeology is briefly described. It is proposed that the concept of traceology can be extended to machined surfaces, particularly those produced by abrasive techniques. A taxonomy of wear marks is outlined which would encompass both pits and scratches. Taxonomic implementations such as the morphology rose and the morphological tree are introduced. The general principles of traceology are illustrated by case studies from criminology, archaeology and abrasive machining processes.

    Abstract [en]

    This master’s thesis was written on the behalf of Saba Frukt och Grönt AB in

    Helsingborg and is the final part of the Master program in Mechanical

    Engineering at Halmstad University.

    The main task was to introduce visual control and increase the rate of concept in

    two of the departments of the company. The goal is to come up with

    implementation proposals, and if possible to implement one in the near future.

    The author attacks the problem by using the Six Sigma DMAIC-methodology as it

    is a clear and structured approach. As a complement Lean-inspired tools are used.

    After compiling the results from the interviews and benchmarking some

    suggestions are made. These are reviewed with stakeholders and a discussion of

    how to go on further was held. Within a short time the implementation starts on

    one department with visual methods such as marks on the floor and an

    andonlamp. Unfortunately, due to time constraints, nothing is yet implemented in

    the other department. However the work is going on and it requires a lot of

    planning and preparation.

    Conclusions are drawn that the goal is achieved and recommendations for future

    work are presented in this master’s report.

    A classification of product sampling for software product lines2018In: SPLC '18 Proceedings of the 22nd International Systems and Software Product Line Conference - Volume 1 / [ed] Berger et al., New York, NY: Association for Computing Machinery (ACM), 2018, p. 1-13Conference paper (Refereed)
    Abstract [en]

    The analysis of software product lines is challenging due to the potentially large number of products, which grow exponentially in terms of the number of features. Product sampling is a technique used to avoid exhaustive testing, which is often infeasible. In this paper, we propose a classification for product sampling techniques and classify the existing literature accordingly. We distinguish the important characteristics of such approaches based on the information used for sampling, the kind of algorithm, and the achieved coverage criteria. Furthermore, we give an overview on existing tools and evaluations of product sampling techniques. We share our insights on the state-of-the-art of product sampling and discuss potential future work. © 2018 Association for Computing Machinery.

    HR-transformationens inverkan på HR-personal2019Independent thesis Basic level (degree of Bachelor), 10 credits / 15 HE creditsStudent thesis
    Abstract [en]

    This study´s purpose is to investigate whether HR staff experience stress relating to an HR transformation. The issues applied to the essay included; the result of the HR transformation, what kind of difficulties it could cause the HR staff, along with how the transformation affects their psychosocial working environment with focus on stress. The study was performed with the help of six informants, who is currently working in an HR department and have in some form participated in an HR-transformation. Data collection was based on semistructured interviews and analyzed with a thematic method. The result showed that half of the informants experienced stress relating to the HR transformation. The HR-transformation resulted in close operational support, visibility in the business, good collegial support and that the HR perspective was included in strategic decisions. Difficulties that arose were ambiguity in the process of change and that the process was time-consuming and working with the new requirements. Confusions about new working methods, unclear division of labor at implementation and an unspoken requirement for constant availability for the business were factors that contributed to perceived stress.

    Ställtidsreduktion med hjälp av SMED2014Independent thesis Basic level (degree of Bachelor), 10 credits / 15 HE creditsStudent thesis
    Abstract [sv]

    Syftet för det här examensarbetet var att praktiskt reducera ställtiden på enbefintlig produktionslinje på Ruukki i Halmstad. Vid tiden då författarna togkontakt med företaget var den nuvarande ställtiden alldeles för lång och långtifrån optimal. I samband med projektets start gjordes det ett antal avgränsningaranpassat till den tiden som fanns tillgänglig.Tillvägagångssättet och metodiken till lösningen bakom ställtidsproblematikenföljer Shigeo Shingos Single Minute Exchange of Die (SMED), där har författarnautfört analyser i form av iakttagelser och tidtagning. Upptäckterna som gjordesunder analys samt implementering var att även om SMED är en direkt metodik förställtidsreduktion finns det andra faktorer som kan motverka implementeringensamt dess goda resultat. Dessa faktorer som påvisades under projektets gång varbland annat de mänskliga aspekterna och den bakomliggande företagskulturen iorganisationen. SMED är en av stöttepelarna för en implementering av Just-In-Time (JIT) som i sig är en viktig beståndsdel av Lean Production.Examensarbetet resulterade i framtagning av en rutin som därefter visualiserades iform av en arbetsmanual. Rutinen testkördes och påvisade gott resultat i form avkortare ställtid.

    Konsultchefers upplevelser i yrkesrollen: En kvalitativ studie om konsultchefers rollhantering, känsloarbete och ledarskap på bemanningsföretag.2011Independent thesis Basic level (degree of Bachelor), 10 credits / 15 HE creditsStudent thesis
    Abstract [sv]

    Vi har undersökt konsultchefer på ett bemanningsföretag. Syftet med studien har varit att ta reda på hur de upplever sina olika roller, vilket känsloarbete de utför i dessa roller, samt hur ledarskapet ser ut i chefsrollen. Vi har utgått från ett individperspektiv och med kvalitativ ansats intervjuat sex konsultchefer på ett bemanningsföretag, för att ta reda på vår frågeställning: Hur upplever konsultcheferna sina olika roller (som chef och säljare) och vilket känsloarbete utför de i rollerna mot konsulter och kunder? Denna har vi besvarat med hjälp av tre huvudsakliga teoretiska ramar: Goffmans (2009) dramaturgiska teori, Hochschilds (2003)teorier om emotionellt arbete och slutligen Sandahl et al.s (2010) teorier om chefens roll i organisationen. Undersökningen visade att konsultcheferna upplever det vara viktigare att “hålla rollen” som säljare mot kunder, än rollen som chef mot konsulter. De använder sig av Surface acting i sitt känsloarbete för att göra kunderna nöjda. Konsultcheferna bearbetar sina “underliggande äkta känslor” genom att samtala med sina kollegor. I rollen som chef är konsultcheferna behandlande mot konsulterna, samtidigt som de leder och styr konsulterna i arbetet.

    The purpose of this study was to explore and understand how leadership is affected when an organization was undergoing a change to an agile business. The background to the survey is based on the traditional view of leadership as the manager led and distributed work. During the 1950s, changed the perception of management and labor in which employees became more involved in the work process.

    Starting from this, our research focused on the effects of leadership that occurs when an organization goes from "command and control" to "empowerment". Hence, we will address the following questions: How has the control (across teams) changed for the line manager in the transition from Classic Waterfall to Agile, How has the change affected the line manager's information retrieval to implement IPM-dialogues and How does the change in style of leadership impact the organization when entering an agile organization.

    We have used a qualitative method in which eight semi-structured interviews were conducted with line managers from two departments to collect the empirical material. The results have indicated that the physical location affects both the control and management style of line managers. Leadership style is also influenced largely by the employees' level of maturity and that the organization is in process of a change.

    Abstract [en]

    This report describes a solution to an adjustment problem found on “The Armadillo”. This product can be described as a bicycle, but with four wheels instead of two, and has a somewhat more complex construction than an electric bicycle. In today’s construction there are difficulties in using the bike if the driver is not within the range of 170-190 cm tall, which obviously limits the user of the product. The main user are those who work with the product. The task of the project was therefore to find a solution to this problem, with free hands without major limitations. This has been done in cooperation the company that owns the product, Velove, where a couple of visits have been made to study the design further, as well as examine the possibilities and limitations that exist. Methods such as Fredy Olsson with small modification have been used, this has simplified the work as a clear structure has been obtained on approaches. The project group has used different ideas to generating and evaluating product ideas, including where we included other students for inspiration, in order to reach a promising concept within the group. Two ready-made digital prototype concepts have been developed in Catia V5, where one of them has advanced into a physical prototype in plastic material. The construction allows a longer span and allows more drivers to use today’s Armadillo. The solution is another smaller rail that goes over the today’s existing rail witch makes it possible to further adjust the length span for the driver. The construction is a superstructure on the existing Armadillo and does not require a reconstruction of the bike.
