Abstract [en]

When developing products, engineering designers often face the problem that their candidate for a technical solution, ranging from a concept to a detailed design, needs to be analyzed by a design analyst before it is approved or rejected and the engineering designer can continue his/her activities within the product development process. If engineering designers have to send every solution candidate to a design analyst, a lot of time and money is lost. To avoid this, some Swedish companies have started to allow their engineering designers to use the analysis capabilities imbedded in modern CAD/CAE software.

          In the literature on product development and on computer based design analysis (CBDA) both processes are fairly well described. However, this cannot be said about the interaction between the two processes. This is a growing issue as it represents core knowledge for developing efficient and effective integration concepts, which in turn can be developed into likewise efficient and effective approaches on how to assist the engineering designer to perform parts of the CBDA process on his/her own. Note that when we refer to CBDA here, this is confined to the use of FEM in the development of products, primarily based on working principles originating from the area of Mechanical Engineering.

          Since we have been working on a process model for the integration between engineering design and design analysis, this has inspired us to utilize findings from these efforts to propose a conceptual model for a design analysis process driven by the engineering designer to be integrated into the product development process.

          The proposed design analysis process model is based on the use of predefined analysis methods or templates. Templates are also utilized for QA (Quality Assurance) and monitoring of the analysis activities. Responsible for the development of the analysis methods and the templates are expert design analysts, who develop these tools within a technology development process. Before allowing the engineering designers access to them, these tools need to be approved by relevant bodies within the industrial enterprise and/or by external sources such as those responsible for certification and risk management.

          In this paper we present the development of the proposed integrated design analysis process model and an industrial case study, which incorporates a non-linear design analysis activity, utilizing the FEM-program Abaqus within the CAD-software Catia V5 and its imbedded optimization module.

Abstract [en]

The current trend in industry to encourage engineering designers to take an active part in the analysis of their own design solutions is apparent in many companies today, domestically as well as abroad.

From a research project with the objective to develop a computer-based design system for the design of lightweight grippers, one of the major difficulties was to overcome the system users’ lack of knowledge and experience in the design of lightweight structures and Computer-Based Design Analysis (CBDA). CBDA here refers to the use of analysis tools such as Finite Element Analysis (FEA) and computer-based structural optimization. In order to handle these difficulties, the author introduced the use of templates. In the given context, a template refers to an especially preformatted code, which contains the implemented information/knowledge necessary to perform a specific task on an operational level. It should be noted that the use of templates as a means of support in performing a specific design or analysis task is not a new phenomenon in industrial practice. Inspired by the opportunities provided by the template approach, the main objective set out for the thesis project was to facilitate the active participation of the engineering designers in performing CBDA singlehandedly, or in any other organizational setting, by utilizing a Template-Based Design Analysis (TBDA) approach, as an integrated part of their activities within the engineering design process.

The evolutionary research approach for the development of the TBDA approach is based on surveys in Swedish as well as international industry, literature surveys, the development of a Generic Design Analysis (GDA) process model (facilitating integration of the activities between CBDA and engineering design) and a number of demonstrator projects to deepen the insights into TBDA. Note that as the TBDA approach is intended for use in industrial practice, the approach is independent of specific engineering design and product development processes utilized in industry.

The conclusion of the thesis work clearly supports the claim that TBDA is not only a competitive approach to current alternatives in supporting the engineering designers performing CBDA, but also of a complementary nature providing functionality not included in the alternative approaches currently used in industrial practice.

Abstract [sv]

Vid framtagning av nya produkter måste man utgå ifrån de behov som den blivande kunden ställer i form av krav och önskemål på produkten för att den ska vara intressant att inhandla och använda. För att säkerställa att den blivande produkten har de egenskaper som efterfrågas, används idag omfattande simuleringar av den blivande produktens egenskaper. Simuleringar består i avancerade beräkningar med hjälp av dator. Genom att utföra dessa tidigt i utvecklingsarbetet, så kan man väsentligen korta ned tiden för utveckling och konstruktion av produkten. Detta uppnås framför allt genom att minska behovet av att bygga och prova prototyper. Beräkningar i utvecklings- och konstruktionsarbetet spelar därför idag en väsentlig roll för att ta fram konkurrenskraftiga produkter på ett snabbt och effektivt sätt.

I denna avhandling har ett nytt tillvägagångssätt tagits fram för att låta konstruktörer själva beräkna sina konstruktionsförslag. Hittills har merparten av alla beräkningar av detta slag genomförts av beräkningsingenjörer. Nu kan man genom att tillämpa den i avhandlingen framtagna tillvägagångssättet att med hjälp av digitala mallar (program för att lösa speciella uppgifter i konstruktionsarbetet) och det föreslagna tillvägagångssättet MallBaserad KonstruktionsAnalys (MBKA) tillåta att konstruktörer, som vanligtvis inte är specialister på beräkningar, självständigt kan utföra sådana analyser. Mallarnas roll är alltså att överbrygga brister i kompetens och erfarenheter av konstruktionsberäkningar.

Redan idag finns konkurrerande sätt att tillåta konstruktörer att delta i beräkningsarbetet, men då oftast med direkt stöd av en beräkningsingenjör och med tillgång till riktlinjer. Dessa kräver att konstruktören har en viss grundkompetens för att kunna följa och tillämpa dessa. MBKA ställer inte dessa krav på kompetens och insikter, vilket gör att den kan betraktas inte bara som en konkurrent till existerande tillvägagångssätt utan också erbjuda ett helt unikt och nytt stöd genom att inte kräva kunskaper och insikter om konstruktionsberäkningar.

Av de reaktioner som erhållits i intervjuer i svensk industri, så ter sig framtiden för MBKA som mycket lovande. Många företag funderar redan idag på att införa tillvägagångssättet. Innan så kan ske, måste dock MBKA utvecklas ytterligare, vilket är målet för den fortsatta forskningen.
