摘　　要：统计分析动车组运维中出现的轮经差故障,总结故障分布规律,从运用径路、设备检测稳定性、车辆部件动作以及产品质量四个方面进行研究分析,结果表明,动车组踏面清扫装置动作模式以及研磨子产品质量对轮径差的产生有较大影响,因此提出了优化研磨子动作模式、批次更换研磨子等管控措施,有效消除了故障。The results of statistical analysis of wheel diameter difference fault in EMU operation and maintenance from four aspects of operation route,equipment detection stability,vehicle component action and product quality show that the action mode of EMU tread cleaning device and the quality of grinding wheel products have a great impact on wheel diameter difference.Measures such as optimizing grinding wheel action mode and replacing them in batches are proposed.The fault is effectively eliminated.
