Abstract

Cushion segment of disc assembly for automobile clutch is taken as research object, a calculation method of forming height for cushion segment is presented based on the analysis of theory of spring back, and it is called reverse trial method. The dimension of forming die for cushion segment is obtained according to reverse trial method, finite element model of bending forming for cushion segment is established. DYNAFORM is used to simulate the spring back of cushion segment, and distribution of stress for forming spring back is analyzed. In addition, forming die is used to verify the forming height by experiment, and the experimental value is 1.55 mm. The results show that the forming height of reverse trial method and simulation are 1.766 mm and 1.63 mm respectively, and the error between reverse trial method and simulation and experiment are 8.34% and 13.94% respectively. Therefore, the correctness of reverse trial method is verified, and it better guides the die design and production of enterprises of cushion segment.
