Taking a kind diaphragm spring of automobile clutch as an example

a finite element analysis based on ANSYS Workbench is studied and explained.Stress and strain variation regulation of diaphragm spring is obtained by using statics analysis

and each rank of modal shape

natural frequency and the maximal deformation are all achieved by applying modal analysis.And the results

a theoretical reference to improving structure design of automotive diaphragm spring clutch is provided.
