引言当轴重超过25t 以后,钢轨出现间距200～300mm 的波浪形磨耗,这是一种常见的现象.波浪磨耗的形成,关系到明显的轨头塑性变形,以及包括轨道与车辆簧下质量在内的共振激励这两个必要条件。虽然在这两个必要条件中,无论消除哪一个都能实现控制波浪磨耗的形成,不过,采用高强度钢轨以限制塑性变形是实惠的方法。Mair 和 Groenhout 从避免发生钢轨波浪形磨耗出发,提出了确定钢轨强度要求的计算
Introduction It is a common phenomenon that when the axle load exceeds 25t, the wavy shape of the rail with 200 ~ 300mm spacing appears. It is a common phenomenon that the formation of wave wear is related to the obvious plastic deformation of the rail head, Resonance within the excitation of these two necessary conditions. Although it is possible to control the formation of wave wear regardless of which of these two prerequisites, the use of high-strength rails to limit the plastic deformation is a cost-effective method. Mair and Groenhout to avoid the occurrence of rail wavy wear, proposed to determine the requirements of rail strength calculation
