曲线上车辆脱轨和钢轨磨耗的原因

Causes to Derailment of Cars on Curve and Wear of Rail

通过对曲线区段列车安全通过和降低轮对轮缘与钢轨磨耗问题的研究,提出将外轨超高降低和把钢轨润滑从外轨改为内轨顶面两点措施,从而减轻了轮缘与轨头的侧向磨耗,提高了车辆运行的安全性。

Via the research on the safe running of trains in curve sections as well as the reduction of wear of the wheelset flange and rail, two measures are taken： reducing the cant and changing the rail lubrication from the outside rail to the inside rail top, so that the side wear between the wheel flange and rail head is reduced, and the safety of car operation is improved.
