Abstract

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.

基于启动条件的干式离合器瞬态温度场的数值研究

摘要

根据车辆启动过程的动力学模型和传热理论，基于流场对流传热系数的时变特性，建立了不同启动条件下的离合器温度场模型。揭示了发动机目标转速、离合器接合压力变化率和道路坡度对温度场分布的影响。将研究结果与之前通过有限元方法获得的结果进行比较。
