从摩擦片的热应力图可以看出，最大热应力发生在内圈表面的约束处，这主要是由应力集中引起的。其余部分的应力不大，即离合器摩擦片的强度和刚度可以满足工作需要。摩擦片的翘曲变形是摩擦离合器的主要失效模式之一，因此主要考虑由加热引起的摩擦片的热变形。加热后摩擦片的变形主要是轴向变形。最大轴向变形为0.5mm，最大变形位于内外缘附近的摩擦面上。因为摩擦片的热应力小于相对材料的屈服强度，<br>这仅是离合器的一次组合引起的温度上升和热变形。在离合器的实际工作过程中，可能会出现不规则或连续的换档过程。由于离合器的频繁分离和组合，与一次性组合相比，摩擦片的温升将大大增加，热应力和应变的分布将更加严重。如下图所示：

It can be seen from the thermal stress diagram of the friction plate that the maximum thermal stress occurs at the constraint of the inner ring surface, which is mainly caused by stress concentration. The stress of the rest parts is not large, that is, the strength and stiffness of the clutch friction plate can meet the work needs. The warping deformation of the friction disc is one of the main failure modes of the friction clutch, so the thermal deformation of the friction disc caused by heating is mainly considered. The deformation of friction sheet after heating is mainly axial deformation.. The maximum axial deformation is 0.5mm, and the maximum deformation is located on the friction surface near the inner and outer edges.. Because the thermal stress of the friction sheet is less than the yield strength of the relative material, it can be considered that the thermal deformation is elastic deformation, which has little influence on the torque transmission capacity of the clutch in the working process.<br>This is only the temperature rise and thermal deformation caused by a one-time combination of the clutch.. In the actual working process of the clutch, there may be irregular or continuous shifting process.. With the frequent separation and combination of the clutch, the temperature rise of the friction plate will be greatly increased, and the distribution of thermal stress and strain will be more serious than under the one-time combination. As shown in the following figure:
