摘　　要：列车车轮多边形磨耗问题广泛存在于我国高速列车车轮上,列车高速运行时会显著增大轮轨之间的相互作用力,严重影响列车运行安全性和舒适性,其产生和发展机理值得全面深入地探究。依托全尺寸轮轨滚动试验台,针对国内某型动车组的拖车轮对,开展高速车轮多边形再现滚动试验,在实验室内再现车轮多边形磨耗产生和发展的整个过程。掌握了车轮多边形磨耗随滚动里程的演变规律,验证了车轮多边形磨耗产生的机理以及发展的关键条件,提出了通过变速运行和严格控制初始轮轨表面不规则状态的车轮多边形磨耗抑制措施。研究结果可为轨道车辆车轮多边形形成机理和抑制措施的相关研究提供重要参考和指导。The polygonal wear of high-speed train wheels occurs commonly and can increase the wheel-rail interaction force dramatically and have a bad effect on the operation safety and comfort of the train.The mechanism on initiation and development of the polygonal wear deserves further study.A high-speed rolling test is performed based on the full-size wheel-rail roller test rig and reproduced the whole process of the initiation and development of the polygonal wear in the laboratory.The mechanism of the initiation and development of the polygonal wear is clearly demonstrated.The evolution progress of the polygonal wear is detailed investigated under different test speed conditions.The effective countermeasures to suppress the polygonal wear development are proposed.The results obtained in the research will be helpful for the further study on the mechanism and countermeasures of the polygonal wear.
