摘要: 车轮镟修是避免铁路车轮非圆化磨耗及其导致的异常振动和关键部件疲劳失效问题的最主要措施。首先通过现场调研分析了不同车轮镟床对重载机车车轮非圆化磨耗消除的影响机制。然后综合运用车辆-轨道耦合动力学理论、刚柔耦合动力学建模技术以及轮轨材料摩擦磨损理论,构建考虑不同镟床镟修车轮后初始非圆化磨耗的重载机车车轮非圆化磨耗演化预测模型;通过数值仿真计算,对比分析采用不同镟床镟修车轮后重载机车车轮非圆化磨耗的演化发展规律。研究结果表明:车轮镟床类型对重载机车车轮非圆化磨耗的消除作用和演化发展影响显著;采用轮对固定效果不佳的镟床无法有效消除车轮高阶非圆化磨耗,镟修后车轮高阶非圆化磨耗发展显著;相比之下,采用轮对固定更为牢固的镟床则可有效避免镟修后车轮高阶非圆化磨耗的残余和演化发展。可为重载机车关键零部件的科学养护维修提供指导。

Abstract: Wheel re-profiling has always been regarded as a main countermeasure to control the development of polygonal wear of railway wheels and to relieve the resulted abnormal vibrations and fatigue fractures of key components. The field investigations are firstly conducted to study the impact of wheel re-profiling lathe on elimination mechanism of polygonal wear of locomotive wheels. Then, a long-term polygonal wear prediction model of locomotive wheels is extended based on the fundamentals of vehicle-track coupled dynamics, rigid-flexible coupled dynamics modeling technology and wheel/rail frictional wear theory. By combining on-site tests and numerical simulations, the influence mechanism of wheel re-profiling lathe on the elimination and evolution of locomotive wheel polygonization is systematically compared and analysed. The investigations point out that the wheel re-profiling lathe affects the elimination and development law of polygonal wear of locomotive wheels to a great extent. The wheel lathe with a poor fixation can’t thoroughly eliminate the high-order wheel polygonal wear; the high-order wheel polygonal wear develops significantly after wheel re-profiling. In contrast, the use of wheel lathes with the stronger wheelset fixation can effectively avoid the residual and development of high-order polygonal wear of locomotive wheels after wheel re-profiling. This study can provide a useful guidance for the scientific maintenance and repair of key components of locomotives.
