| 摘 要： | 南京地铁车辆轮对磨耗情况严重.原因除轮、轨匹配的因素外,还发现制动系统可能存在过度的问题.通过不同驾驶模式下踏面外形的对比,分析认为:踏面凹陷磨损的问题和制动过于频繁有一定关系,要改善踏面凹痕磨耗还需要从轮轨接触面考虑,为彻底解决异常磨耗问题,只需要设计踏面外形.

| Abstract: | Due to the severe tread wear of wheelsets, this paper analyses the reasons of wheelset wear, including the wheel-rail mate,the over-load brake force and ATC(ATO) mode in Nanjing metor cars,discusses the influence of drive mode on tread unusual wear of wheelset, argues that all air-brake should not be imposed freguently and the tread be well designed. |
