摘　　要：对于摩擦离合器接合过程系统承载复杂,相关研究文献较少的现象,基于有限元数值仿真算法,以某湿式多片摩擦离合器为研究对象,考虑不同转速工况下,研究离合器接合过程中摩擦片的温度响应及热应力响应。研究表明,在不同转速工况下,摩擦片达到热平衡的时间基本相同,离合器系统达到热平衡时间随着转速的增大而增大;摩擦表面和非摩擦表面的温度上升及下降趋势有明显不同。To the situation that the load act on the joint system of the friction clutch is complicated, and the research on this field is rarely, based on the finite-element numerical simulation method, took a wet multi-disc friction clutch as object of the research, considered the different speed conditions, the temperature response and the thermal stress response of the jointing process of the clutch is researched. The result shows that, the friction plate reach thermal equilibrium spend the same time at different speed conditions, and the clutch system spend more time when the speed is faster; the rising trend and the downtrend of the temperature between friction surface and others surface is different.
