摘　　要：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。Plastic deformation of the wheel and rail in contact is analyzed with the elasto plastic theory. A concept of shakedown limit for wheel and rail materials under elasto plastic condition is proposed. Based on this concept, the plastic deformation of the contacting wheel rail is predicted by means of calculation.
