To solve the fracture problem of clutch pressure plate, a model for analyzing the thermal deformation and stress of pressure plate is built with consideration of the changes in axial nonlinear characteristics of waved plate and friction coefficient with rotating speed difference. With the model, the temperature distribution during the engaging process of pressure plate is simulated and verified by real measurement. Based on analysis results, modification schemes for pressure plate are proposed, a sample part is produced and real vehicle test is performed with no fracture of pressure plate happened, demonstrating the correctness of modeling and analyses.
