摘要

在湿式离合器接合过程中，温度对离合器的摩擦学特性和磨损失效起着至关重要的作用。基于锥形接头的联合磨损规律，计算了接触压力分布和摩擦热流密度，建立了具有详细结构的多锥形摩擦片三维瞬态热分析有限元模型。分析了不同工况对摩擦片最高瞬态温度的影响，给出了指定位置的温度和径向分布。结果表明:最高温度出现在接合期中期附近，位于锥顶边缘。内锥面温度高于外锥面温度。

Thermal Behavior of Multi-Conical Wet Clutch based on Combined Wear Law

The temperature plays a vital role in the tribology properties and failures of scuffing and excessive wear during the engagement of wet clutch. The contact pressure distribution and friction heat flux have been calculated based on the combined wear law of the conical joint, and a three-dimensional transient thermal analysis finite element (FE) model with the detailed structure for the multi-conical friction plate is established. The influence of different operating conditions on the highest transient temperature of friction plate is analyzed, and the temperature of the specified location and the radial distribution are given. The results show that the highest temperature appears near the middle of the engagement period and locates at the edge line of the cone top. The temperature of inner conical surface is higher than that of the outer conical surface.
