This paper considers the diaphragm spring of a mechanical clutch being composed by a conical disk spring and trapezoidal lamellar springs attached to the disk spring. After analytical calculation of the disk spring a numerical structural analysis was performed in order to validate the 3D model of the disk spring. A design optimization with 4 design variables was done for the disk spring and, based on the optimized design, the 3D model of the diaphragm spring was built. A 6 design variables model of the diaphragm spring was proposed for design optimization analysis having as design objective the minimization of the maximum equivalent stress during disengaging the clutch.
