摘要: 车轮失圆是铁路轮轨列车较为常见的问题之一,对车辆运行安全和轮对维护具有较大影响。通过对80 km/h速度级B型地铁车辆车轮不圆度进行大量测试,发现测试的6条线路中有5条线路车轮主要表现为偏心磨损,且车轮失圆发展非常缓慢,仅1条线路的车轮失圆较为严重,主要表现为偏心和5~8边形。失圆严重的车轮存在明显凹形磨耗,并且闸瓦-车轮匹配关系较差,闸瓦不能起到圆度修形作用,导致车轮失圆发展较快。根据现场调研和试验结果分析,提出了降低列车启动加速度、改善闸瓦-车轮匹配关系和降低轮轨动力作用等措施减缓车轮失圆的发展。根据车轮失圆对车辆动力学性能影响的仿真分析,提出了车轮低阶多边形的镟修限值,建议采用径跳0.4 mm的统一限值对低阶失圆车轮进行镟修。

Abstract: Wheel out-of-roundness(OOR) is a common problem in railway industry, which has a great influence on vehicle running safety and wheelset maintenance. Wheel OOR of type B metro train has been investigated through extensive field measurement on six metro lines. The measurement results indicate that most of wheels on five of six metro lines exhibit eccentricity and the development of wheel OOR is very slow. However, wheels on the other one metro line suffer from serious OOR problems with eccentricity and orders 5-8. The wheels with serious OOR exhibits obvious hollow wear on the wheel tread, and the matching relationship between brake shoe and wheel tread is poor. The repairment function of brake shoe for wheel OOR is lost, which leads to rapid development of wheel OOR. According to field investigation and analysis of test results, three measures are proposed to reduce the development of wheel OOR, including reducing the starting acceleration, improving the matching relationship between brake shoe and wheel tread and reducing the dynamic wheel/rail interaction. Wheel re-profiling threshold value is proposed based on the influence of wheel OOR on vehicle dynamics performance. The recommendation maximum allowable value of the radial run-out of wheels is 0.4 mm for low order OOR.

Key words: type B metro train, wheel out-of-roundness, wheel wear, wheel re-profiling, mitigation measure
