摘要: 磨耗与滚动接触疲劳是动车组车轮的两种主要损伤形式,为对实际线路上运行的动车组车轮损伤进行预测。首先通过动力学软件UM建立复兴号动车组模型,根据实际高速铁路线路工况参数设计四个典型线路工况,将四个典型线路工况组合并进行动力学仿真,基于车辆模型的安全性和舒适性计算,验证车辆模型的有效性。通过各典型线路工况单独仿真下的轮轨蠕滑力及轮轨蠕滑率并结合车轮损伤函数,计算并获取各典型工况下的车轮磨耗及滚动接触疲劳损伤,基于损伤累积原则获取各典型线路工况下车轮损伤的累积值,与完整的组合线路工况下一次性仿真结果计算的车轮损伤进行对比,验证基于单独工况累积损伤预测组合工况损伤的可行性,同时进一步基于该原理对任意两种组合工况下的车轮损伤进行了预测,该方法为未来车轮损伤预测提供了一种高效且准确的新途径。

Abstract: Wear and rolling contact fatigue are the two main forms of damage to the wheels of high-speed trains. To predict the damage to the wheels of high-speed trains operating on actual lines, a model of the Fuxing high-speed train is first established using dynamic software UM. Four typical line conditions are designed based on actual high-speed railway line conditions parameters. The four typical line conditions are combined and dynamically simulated. Based on the safety and comfort calculation of the vehicle model, the effectiveness of the vehicle model is verified. By separately simulating the wheel-rail creep force and wheel-rail creep rate under each typical line working condition, combined with the wheel damage function, the wheel wear and rolling contact fatigue damage under each typical working condition are calculated and obtained. Based on the damage accumulation principle, the cumulative damage of the wheels under each typical line working condition combination is obtained. Compared with the one time simulation results under the completed and combined line working condition, the feasibility of predicting combined working condition damage based on individual working condition cumulative damage is verified. Furthermore, based on this principle, the wheel damage under any two combined working conditions is predicted, providing an efficient and accurate new approach for future wheel damage prediction.

Key words: wear, rolling contact fatigue, combined line working condition, EMU wheels, damage prediction
