Thermal-stress Coupling Analysis And Improvement Research Of Φ430 Clutch Pressure Plate

In this paper, a type of 0430 clutch pressure plate produced by certain company is analyzed. Deformation, erosion and cracking phenomena during using, which may lead to early failure of the clutch pressure plate was analyzed numerically. The material and manufacturing process is considered to be one of the factors leading to the failure of pressure plate based on the hardness tests of the friction surface. What's more, nonlinear finite element code ABAQUS is employed for the simulation. The temperature field and the thermal stress field were obtained depending on working conditions of the clutch. According to the result, the danger point centralized on the outer edges and the mounting holes of the friction surface. The main reason of the damage of the pressure plate is the insufficient strength when working in the heavy-load condition. Based on the analysis, a new type of air-cooling pressure plate is developed. The developed pressure plate reduces the thermal stress and deformation caused by the solid structure, which improves the efficiency of the vehicle. The conclusion is of significant meaning for improving the reliability of the pressure plate.
