摘要

结合湿式多片离合器实际结构和工作条件，运用Abaqus软件建立湿式离合器有限元分析模型，采用热结构直接耦合法对湿式离合器工作过程中摩擦副的温度场进行分析，研究了湿式离合器活塞的不同加压方式对摩擦副温度场的影响规律。研究结果表明，加压方式对对偶钢片的温度场具有重要影响，尤其是，对直接受活塞作用的对偶钢片影响最为明显；局部加压方式下各时刻最高温度均大于均匀加压方式下各时刻最高温度，且局部加压方式最高温度出现时刻较早；局部加压方式下对偶钢片表面高温带宽更窄，径向温度梯度更大。

Abstract

Based on the actual structure and work conditions of wet multi-disc clutch, a finite element analysis model of wet clutch is established by using Abaqus. The temperature field of friction pairs in wet clutch is analyzed by the direct thermal structure coupling method，and the influence of the applied load way of piston in wet clutch on the temperature field of friction pairs is studied. The results show that the applied load way has an important effect on the temperature field of separator plate，and the most obvious effect is on the separator plate which is directly affected by the piston. The maximum temperature under partial load way is higher than that under uniform load way and the maximum temperature under partial load way appears earlier. The bandwidth of high temperature on separator plate is narrower and the radial temperature gradient is larger which under partial load way.
