【摘要】 针对铁路列车制动闸片摩擦块排布方式对制动盘热机耦合响应状态影响显著的问题，提出了一种考虑接触压力分布和非均匀热流密度的热机耦合仿真分析方法。通过在轨道车辆制动性能试验台上进行的制动台架试验，从温度的角度验证了所提方法的正确性。在此基础上，建立了列车全尺寸盘型制动系统有限元仿真分析模型，对现有铁路列车制动闸片摩擦块的排布方式进行了优化分析。结果表明，合理的制动闸片摩擦块排布方式可以显著降低制动盘面的温度和应力峰值，在改善制动盘面温度和应力分布的同时，提供较为优异的制动性能。研究成果可为铁路列车盘型制动系统热机耦合分析提供一种快速有效的仿真分析方法，同时可为铁路列车制动闸片摩擦块的排布优化提供指导方向。更多还原

【Abstract】 The friction block arrangement has a significant influence on the thermo-mechanical response status of the brake disc. A thermo-mechanical simulation method considering the influence of contact pressure distribution and non-uniform heat flux density is proposed. The experimental test data obtained by the railway vehicle braking performance test bench is used to validate the correctness of the proposed method from the perspective of temperature. After that, the full-size finite element model of the railway disc brake system is established and the existing friction block arrangement is optimized. The results indicate that a reasonable arrangement of friction blocks can significantly reduce the highest temperature and stress, improve the distribution of temperature and stress on the brake disc, and provide good braking performance. This work can provide a fast and effective simulation method for thermo-mechanical analysis of railway disc brake systems and provide guidance for friction block arrangement optimization.更多还原
