根据高原山区重载运输车辆轮毂技术参数及实际使用工况,使用COMSOL Multiphysics软件对连续制动情下制动鼓及轴承温度场分布及温升过程进行模拟仿真分析.结果表明:在高原山区特殊路况下连续制动时,重载车辆动鼓与刹车片摩擦表面的温度在430~580℃之间;轮毂轴承温度随着制动时间增长逐步上升,在150~210℃之间;续制动导致车辆轮毂轴承温度明显升高是造成轮毂轴承润滑脂流失失效的主要原因.

According to the technic parameter and working condition of trucks operated under heavy loading and moun-tain driving at altiplano region,the distributing of temperature field and the process of temperature rising of the break drum under frequent breaking were analyzed through computer simulation by COMSOL Multiphysics. The results show that tem-perature between brake drum and block ranges from 430 ℃ to 580 ℃ and the temperature of drum ranges from 150 ℃ to 210 ℃ under continuous braking. Continuous braking is the major reason for lubricating grease loss failure of high tempera-ture.
