摘要
为了探讨车轮旋修后机加工接触面和钢轨之间以及光滑接触面和钢轨之间的瞬态特性,用一对小型圆柱试样进行了切向力试验,以期研究车轮旋修对车轮爬轨脱轨的影响。
To investigate transient characteristics between machined contact surfaces and rail,and between smooth contact surfaces and rail after wheel turning,tangential force experiments were carried out using a pair of small cylindrical specimens,so as to study the influence of wheel turning on wheel climb derailment.
