The AMT clutch pressure plate temperature rise characteristics with different thickness of pressure plate under different working environments are studied. Firstly,the 3D model of clutch pressure plate is established based on the structural parameter of clutch. Then,the influence factor of the temperature rise variation is analyzed,and according to the clutch pressure plate working environment,the thermal boundary condition is determined. Lastly,by using the ANSYS,the clutch pressure plate finite element thermal analysis is carried out,and the temperature rise curves of different thickness of pressure plate under different working condition are got. A good reference for the structural optimum of AMT clutch and the using control policy of clutch can be provided by the research result.
