利用ANSYS软件研究重载铁路货车轴承弹塑性接触行为，将其简化为单峰接触模型，分析材料应变硬化对重载铁路货车轴承弹塑性接触的影响。取不同的切线模量值，研究应变硬化的影响，结果表明，应变硬化对弹塑性接触参数的影响不同，随硬化参数值的增加，对其影响效应也增加；对于较高的硬化参数，应变硬化对弹塑性接触的影响更大；随应变硬化增大，材料抵抗变形的能力增强，能够在较小的接触面上承受较大的载荷。

The ANSYS software is used to study elastic-plastic contact behavior for heavy load railway freight bearings which can be simplified as a single peak contact model to analyze the effect of material strain hardening on elastic -plastic contact of heavy load railway freight bearings.The different values of tangent modulus are taken to study the effect of strain hardening.The results show that a generalized solution cannot be applicable for all kind of materials, because the effects of strain hardening on elastic-plastic contact parameters are different.With the hardening parame-ter value increases,the strain hardening effect is also increased on elastic-plastic contact.For higher hardening param-eter,the effect of strain hardening on contact is serious.With the increase in strain hardening,the deformation resist-ibility capacity of material is increased,and the material becomes capable of carrying higher load in a smaller contact area.
