摘　　要：本文提出在制动盘热机耦合分析时考虑安全余量,以200 km/h高速列车为例,设计了4种安全余量仿真方案,分析两次紧急制动工况下制动盘温度场和应力场,结果表明增加减速度方案的计算安全系数最高,增加速度方案的计算安全系数最低,增加轴重方案和降低制动盘许用范围方案居中。An innovative idea of taking consideration of safety margin during disc thermal-mechanical coupling analysis was proposed. One high speed train at 200 km/h as research model was taken for 4 different working conditions about safety margin in simulation. It aimed to analyze simulation results of temperature field and thermal stress field of braking disc after twice urgent braking. The outcomes obtained showed that the calculated safety factor would be the biggest under “de-celeration” condition, while the “acceleration” condition results in the smallest factor. Two other suppositions of “addition of axle load” and “reduction of allowable disc area” are mediate.
