在轮轨关系研究中，横移是一个非常重要的工况参数。横移量的变化将极大地影响接触斑上的几何参数和力学参数。本文的研究将着重讨论横移量对轨头内弹塑性接触应力场的影响。研究得到，横移量对轨头内塑性区、应力状态的分布都有很大的影响。
In the wheel-rail relationship study, traversing is a very important condition parameter. Changes in the amount of traverse will greatly affect the geometry and mechanical parameters of the contact patch. In this paper, the research will focus on the impact of transverse displacement on the elastic-plastic contact stress field in the rail head. The results show that the amount of lateral displacement has a great influence on the distribution of plastic zone and stress state in the rail head.
