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
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.
