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.
