摘　　要：采用大型有限元分析软件ANSYS对轮对压装过程进行接触问题的动态有限元分析,模型采用HXD2型电力机车的轮对模型,轮轴材料采用课题组得到的轮轴应力应变本构曲线。通过采用不同的过盈量,摩擦系数进行仿真分析,得到其对轮毂孔、轮座面的Mises应力沿轮轴接触面轴向位置的分布的影响,以及其对压装压力曲线的影响。同时还将根据得到的压装压力曲线及实际图纸要求的过盈量来为本轮对压装时采用的摩擦系数得出一定的范围,供实际应用参考。The finite element analysis software ANSYS was used to make the dynamic finite element analysis of contact problem during wheelset fitting. HXD2 electric locomotive wheelset model will be used. Using the stress-strain curves of the materials which is obtained by studying team.Using different amount of intelference, friction coefficient to make Simulation analysis to get the accurate stress distribution of the surface of wheel-hole and wheel-seat along the axial pasition , as well as the pressure curve. At the same time we will use the pressure curve and the actual amount of interference to get a certain range of friction coefficient, for the practicalapplication of reference.
