NUMERICAL INVESTIGATION OF THE TRANSIENT TEMPERATURE FIELD OF A DRY CLUTCH BASED ON STARTING CONDITIONS

摘要

According to the dynamic model of the vehicle starting process and the theory of heat transfer, a clutch temperature field model under different starting conditions is established based on the time-varying characteristics of the convective heat transfer coefficient of the flow field. The effects of the engine target speed, clutch engagement pressure change rate, and road gradient on the temperature field distribution are revealed. The results of the study are compared with those obtained earlier by the finite element method.
