# The Diaphragm Spring Characteristics

In this chapter, Express the result and discuss about the diaphragm spring characteristics, which is affecting the overall performance of an automobile. In last chapter, applied some load on the diaphragm spring different designs. Moreover, define some characteristics such as total deformation, directional deformation, equivalent elastic strain, equivalent stress, maximum principal stress and strain energy. They are affecting the performance of the diaphragm spring clutch. The aim of this study is to define the change of the maximum reaction force related to diaphragm spring thickness and upper side support point location. While FEM solution is preparing, Ansys and Cre-o program work and communicate each other. Diaphragm spring

The graph 5.1 shows the variation in total deformation for following five designs (1, 2, 3, 4, and 5). The obtained result concludes that the design having the least total deformation is 5. The lesser variation in total deformation results in stability and higher strength. The design 5 is considered as best amongst all.

2. The graph 5.2 shows the variation in directional deformation for following five designs (1, 2, 3, 4, and 5). The obtained result concludes that the design having the least directional deformation is 5. The lesser variation in directional deformation results in stability and higher strength.

3. The graph 5.3 shows the variation in equivalent elastic strain for following five designs (1, 2, 3, 4, and 5). The lesser variation in equivalent elastic strain results in stability and higher strength. 5 are considered as the best design.

4. The graph 5.4 shows the variation in equivalent stress for following five designs (1, 2, 3, 4, and 5). The lesser variation in equivalent stress results in stability and higher strength. For equivalent stress, the minimum stress is obtained in 5

These are explained as follows-

The following interpretation can be made from above graphs for 100N load:

1. The graph 5.7 shows the variation in total deformation for following five designs (1, 2, 3, 4, and 5). The obtained result concludes that the design having the least total deformation is 5. The lesser variation in total deformation results in stability and higher strength. The design 5 is considered as best amongst all.

2. The graph 5.8 shows the variation in directional deformation for following five designs (1, 2, 3, 4, and 5). The obtained result concludes that the design having the least directional deformation is 5. The lesser variation in directional deformation results in stability and higher strength.

3. The graph 5.9 shows the variation in equivalent elastic strain for following five designs (1, 2, 3, 4, and 5). The lesser variation in equivalent elastic strain results in stability and higher strength. 5 are considered as the best
