Design Optimization of the Diaphragm Spring of a Mechanical Clutch for Motor Cars

Abstract

In this paper it is presented the design optimization of the diaphragm spring for a mechanical clutch. The slot shape of the fingers was parameterized and the objective function was the maximum tangential stress to be minimized subjected to the constraint that the deflection of the spring on exterior diameter in the spring centreline direction has a minimum certain value when the clutch is disengaged.
