1.前言长期以来,虽然进行了大量研究,并在机车运用方面积累了丰富经验,但运动的车轮同钢轨之间的粘着作用始终未得到充分的探讨。其原因是由于轮轨相互作用时出现的这一现象极其错综复杂。在先前进行的研究里,一直是根据弹性理论和通过分析那些能确定轮箍与钢轨材料变形及其相互作用力的试验结果而对粘着的宏观过程进行探讨的。由于轮箍与钢轨的接触面在相对运动中相互作用,故假设通过探讨轮箍和钢轨材料基本
1. Foreword Although a great deal of research has been carried out for a long time and accumulated rich experience in locomotive operation, the adhesion between the wheel of the sport and the rail has not been fully explored. The reason is that this phenomenon is extremely complicated due to the interaction between wheel and rail. In previous studies, the macroscopic process of adhesion has been explored on the basis of elastic theory and by analyzing the results of tests that determine the deformation of the wheel and rail material and their interaction forces. Due to the interaction between the wheel rim and the rail surface in the relative motion, it is assumed that by discussing the wheel base material and the rail material
