运用弹塑性理论分析了轮、轨接触工况时的塑性变形，提出了轮轨材料在弹塑性状态下安定极限值的概念，并依此进行了轮轨接触计算，预测了轮轨廓形的塑性变形值
Based on the theory of elasto-plasticity, the plastic deformation of the wheel-rail contact condition is analyzed. The concept of the stability limit value of the wheel-rail material in the elasto-plastic state is put forward, and the wheel-rail contact calculation is carried out to predict the wheel-rail profile Plastic deformation value
