摘要/Abstract

摘要： 列车车轮多边形磨耗会显著加大轮轨相互作用力和转向架关键部件振动幅度，恶化车辆系统和轨道部件的工作环境，严重时将会威胁到行车安全。基于三维车辆-轨道耦合动力学模型，用谐波叠加法模拟车轮多边形磨耗，作为车辆轨道耦合动态行为分析时的激励输入，计算车轮多边形磨耗阶次、车辆运行速度和运行里程对轮轨力的影响，并分析车轮多边形磨耗与轮轨力之间的相位关系；建立转向架系统高频振动全有限元模型，以时域轮轨力作为模型输入，分析车轮多边形磨耗参数对转向架轴箱、构架振动响应的影响。计算结果显示，随着列车运行速度、车轮多边形磨耗幅值和阶数的提高，轮轨垂向作用力波动范围和转向架振动响应均会显著增大。所得的结果可为高速列车车轮多边形形成的机理和抑制措施的进一步研究提供参考和指导。

Abstract: The polygonal wheels of high-speed trains will increase the wheel-rail vertical force dramatically and have a bad effect on the components of the vehicles and rails. Then the safety of the trains can't be assured. The damage of bogie's components is found through site testing which related to high-order polygonal wear of wheels. The vehicle-track coupling dynamics model with polygonal wheels is established. The effect of amplitude and order of polygonal wear and running speed on wheel/rail force and acceleration of the wheelsets and the bogies is invested. The results show that the higher speed of the train and amplitude and order of wheel polygon can lead to the higher wheel/rail force and the higher acceleration. The results obtained in this investigation may be helpful for the further study on the mechanism of polygonal wear of the wheels.

Key words: high-frequency vibration, high-speed train, polygonal wear, train/track coupling dynamics model, wheel/rail contact force
