摘要:
［目的］CR200J型动车组拖车及控制车在某些区段出现稳定性报警故障，为了分析故障原因和解决故障问题，需对影响动力学性能的因素进行深入研究。［方法］对某组CR200J型动车组拖车和控制车车轮磨耗状态进行了跟踪测量，并对该动车组开行交路的钢轨廓形进行了实际测量；通过SIMPACK软件仿真，结合实际轮轨匹配关系，分析了车轮磨耗对车辆动力学性能的影响。［结果及结论］CR200J型动车组的拖车和控制车的车轮磨耗主要为滚动圆处集中磨耗；随着车轮磨耗增加，轮轨接触关系发生改变，车轮等效锥度线性增大，车辆横向平稳性指标变化明显；实测个别路段轨道廓形存在突变，转向架出现横向谐波运动；最后，根据车轮磨耗规律和特点，提出改进建议。
Abstracts:
［Objective］ In response to stability alarm faults occurring in CR200J EMU trailer and control cars in certain sections, it is necessary to analyze the factors affecting the dynamics performance to analyze the causes and address the issues. ［Method］ Tracked measurements are conducted on the wheel wear status of a set of CR200J EMU trailer and control cars. The actual rail profiles along the operating routes of vehicles are measured to identify the development patterns of wheel wear. Through SIMPACK software simulation, and combined with real wheel-rail matching conditions, the impact of wheel wear on vehicle dynamics performance is analyzed. ［Result & Conclusion］ The wheel wear of CR200J EMU trailer and control cars mainly concentrates at the rolling circle. As wheel wear increases, changes occur in the wheel-rail contact relationship, leading to a linear increase in wheel equivalent conicity, and noticeable changes in lateral stability indicators of the vehicles. Some sections of the measured track profiles exhibit abrupt changes, causing lateral harmonic motion in the bogies. Finally, based on the patterns and characteristics of wheel wear, improvement suggestions are proposed.
