摘要: 车轮非圆化磨耗是铁道车辆常见的一种车轮磨耗形式,对车辆的振动、噪声、乘坐舒适性和运行安全性均具有较大影响。介绍车轮非圆化的表现形式,总结国内外轮轨轨道交通车辆运营中出现的车轮非圆化磨耗现象。重点总结车轮非圆化磨耗的形成机理,根据车轮非圆化磨耗形成原因的不同将其分成三大类:由车轮初始缺陷引起的非圆化;由车辆-轨道固有振动引起的非圆化;由踏面制动时闸瓦与车轮间热弹性失稳引起的非圆化。回顾车轮非圆化磨耗仿真的研究历程,指出当前车轮非圆化磨耗研究面临的难点和挑战。对车轮非圆化磨耗的控制措施进行总结,重点讨论改善车轮镟修质量、利用闸瓦或研磨子修复车轮非圆化这两个最主要措施。探讨针对车轮非圆化磨耗亟需开展的研究,可为车轮非圆化磨耗机理的研究和控制措施的选用与实施提供参考。

Abstract: Wheel out-of-roundness(OOR) is a common form of wheel wear in railway vehicles, which has a great impact on the vibration, noise, riding comfort and operation safety of vehicles. The feature of each type of OOR is introduced, and some phenomena of OOR in the railway transportation field around the world are summarized. The formation mechanism of wheel OOR is mainly summarized. According to the different causes of OOR, it can be divided into three categories: 1) OOR resulting from the initial defects of the wheel, 2) OOR resulting from the inherent vibration of the vehicle and track, and 3) OOR resulting from the thermos-elasticinstability by tread braking. The research process of OOR wear simulation is reviewed, and the difficulties and challenges of current OOR simulation are pointed out. Moreover, the countermeasures of OOR are summarized, focusing on the improvement of wheel re-profiling quality and the repair of OOR with brake shoe or wheel tread cleaner. What still needs to be further carried out on the OOR is discussed. A reference is provided for the research of OOR mechanism and the selection and implementation of wheel OOR mitigation measures.

Key words: railway vehicle, wheel out-of-roundness, wear mechanism, mitigation measure
