摘　　要：在摩擦离合器接合过程动力学分析的基础上,建立了摩擦片热分析数学模型,并利用MATLAB对摩擦片温度场进行了仿真分析。结果显示摩擦片表面温度随着时间成正比例增长,温升值随着摩擦片半径大小呈线性分布,并与外部载荷有关。该分析为摩擦离合器热变形分析提供了一定的理论依据。Thermal analysis mathematical model of clutch friction plate was established, based on engagement dynamic analysis of its, temperature field of its was simulated using MATLAB, and finally demonstrated that surface temperature becomes the proportion along with the time to grow, temperature - rise assumes linear distribution along with radius size of friction plate, and concems with exterior load. This analysis provides theory basis for friction clutch thermal deformation analysis.
