Coupling heat stress analysis of the friction disk in clutch

The clutch is an integral of the automotive transmission system,where as friction disk,a major part of the clutch,impacts significantly on clutch performance.In order to improve its performance,a finite element technology was employed for friction disk coupling heat stress.Based on the established physical model of heat conduction in engaging process of clutch,the finite elements were analyzed to acquire the temperature distribution and heat distribution of friction disk under thermal loads.The experimental results show that it is significant for the design and use of clutch.
