热机现象对湿式多片制动器设计的影响

产生于滑动盘片间的热机现象对湿式多片制动器的衬片压力和表面温度分布具有显著的影响，并已成为制动器破坏的主要原因之一。为了降低热机作用的影响，对对流换热系数、摩擦系数、摩擦速度和初始衬片压力分布等一些重要的设计和材料参数进行了详细的分析，针对湿式多片制动器设计方法提出了等温度设计的新观点。

Influence of Thermomechanical Phenomena on Design of Multiple Disc Wet Brakes

Thermomechanical phenomena occurring between sliding plates greatly change the distributions of lining pressure and friction surface temperature of a multiple disc wet brake. It has become one of the main causes of a brake failure. In order to reduce the undesirable thermomechanical effects, several design and material factors influencing on thermomechanical phenomena, such as heat transfer coefficient, friction coefficient, sliding velocity, initial lining pressure and so on, were analyzed, and a new viewpoint - isothermal design method was proposed for designing multiple disc wet brakes.
