通过轮轨断面形状研究轮轨接触状况

Investigation of Wheel and Rail Contact States by the Profile of Wheel and Rail

本文从车轮与钢轨头顶面曲率和斜度的关系对轮轨接触形状进行了研究。除了对新轮新轨进行了计算外,还对运用中的轮轨磨耗形状进行了研究。研究结果将给出会不会引起二点接触以及接触应力是怎样变化的。这不仅对于重载运输中轮轨形状的选择,也对轮轨磨耗的研究提供了一种有用的方法。

In this paper, the contact profile for wheel and rail tread was researched fro the relationship for the curvature of profile and the slope. Apart from the new wheel and the new rail, it can be also able to investigate the worn profile of wheel/rail caused by operating. The results of research will give the judgement to understand that whether two point contact is occurred or not and how to exert in the contact stress of wheel/rail. Thus, this is useful to select the profile of wheel/rail in this case of heavy haul railway and to research the wear of wheel/rail.
