摘　　要：机车晃车是列车运行品质不良的典型表现,是机车在运行中对于某些轨道状态不良的动力响应。本文应用机车车辆轨道动力学原理分析了直线地段钢轨交替不均匀侧磨、轨道轨向与水平逆相位复合不平顺等易引发机车晃车的主要因素,并分别提出了针对性的预防措施。The swing of locomotive is a typical characteristic of unfavorable train running,which is happened by the dynamic respondency of the locomotive during speeding up on the track without good conditions.This article analyses the main causes of the swing of locomotive,occurred by the asymmetry side wear of linear track,track alignment and cross-lever irregularities. And therefore, it presents preventive measures correspondingly.
