在研究机车车轮的滚动接触疲劳时，以往机械设计文献所采用的方法不完善，资料不完全。建议将纯滚动和纯滑动时的最大正文剪应力作为两个界限术研究机车车轮的滚动接触疲劳，并针对东风系列机车给出了有关计算资料。还指出了有切向力时最大正交剪应力的特点。 When studying rolling contact fatigue of locomotive wheels, the methods used in the past mechanical design literature are not perfect and the data are not complete. It is suggested that the maximum body shear stress of pure rolling and pure sliding should be used as two limit techniques to study the rolling contact fatigue of locomotive wheels and the calculation data are given for the Dongfeng series locomotives. The characteristics of the maximum orthogonal shear stress with tangential force are also pointed out.
