Thermal Effects Analysis on DCT Driven Plate in Vehicle Initial Condition

Abstract:

The Dry-type Dual Clutch system is designed for a certain Dual Clutch Transmission (DCT), and transient analysis is performed to investigate the thermal influence on driven plate in sophisticated slip conditions, which is determined by control strategy of DCT. First, a clutch engagement model is developed to obtain transient friction power corresponding to selected control strategy, and the distribution of time-varying heat flux is derived. On that basis, the thermal effects on the driven plate are simulated by finite element method. Finally, the temperature and thermal stress distributions on the frictional surfaces are acquired, which shows that the previously designed clutch system agrees with thermo requirements. This new approach which is more superior to the traditional clutch analysis, can adjust to different control strategies, thus it can be applied to facilitate the thermo analysis and practical design of DCT system.
