摘要
采用高度非线性有限元软件MSC.Marc建立热机耦合的3D模型,模拟了200 km/h高速列车制动盘制动过程中温度和应力变化情况,分析了制动过程中温度和应力的变化规律。数值模拟结果与1:1制动台架试验结果相吻合。可为新型高速列车制动盘的研制提供参考。
The varied behavior of temperature and stress in disc was simulated in the duration of 200km/h high-speed train braking, the highly nonlinear finite element analysis software MSC.Marc was adopted to build coupled thermo-mechanical three-dimensional models. The changing rule of the temperature and stress field was also analyzed. The results were coincided with the 1：1 dynamic bench test. These can provide references to study new high-speed strain discs.
