摘要

为研究ULF 轻轨列车制动盘在制动时温度场以及热应力的分布情况，对其建立了三维有限元模型，通过对制动盘施加合适的边界条件，模拟制动盘在工作状况下热流的产生以及热量的散失，并通过ABAQUS 进行求解。其结果表明在制动过程中制动盘温度随时间先急剧上升而后下降，且沿径向递增，无稳态传热过程。制动盘热应力分布与温度场分布相关，但是制动盘热应力由内圆周沿径向先递减后递增，最大应力位置出现在制动盘边缘。因此，对于热应力而言，制动盘边缘为其薄弱部位。

Abstract

To research the distribution of temperature filed and the thermal stress of ULF light rail trains, the three-dimensional finite element model was constructed, and according to apply proper boundary condition to the brake disc , the heat flux generation and the heat dissipation of brake disc were simulated and computed by ABAQUS. The result showed that in the process of brake, the temperature of brake disc rose severely at first and then decreased with time, and increased in the radial direction without steady-state heat transfer. The distribution of thermal stress was related to the temperature field.However,the thermal stress of the brake disk increased after the inner circumference decreased first. The maximal thermal stress appeared in the edge of the brake disc. Therefore, the weak part is its edge for brake disc.
