中文摘要：

为了探究装配过盈量，摩擦因数，形状公差，轮轴突悬组装以及注油槽对压装曲线及轮轴接触部位应力的影响规律，以某型动车组轮对为研究对象，用ABAQUS软件建立轴对称有限元模型，对轮对压装过程进行仿真。研究结果表明：配合过盈量以及摩擦因数是确保配合质量达标的关键；轮轴突悬组装、车轮注油槽对接触部位的应力分布有显著影响；选择恰当的轮轴形状误差组合有利于压装的合格。

英文摘要：

In order to investigate the effect of interference, friction coefficient, shape error, protruding assembly,oiling groove on the press-fit curve and stress of contact position, an axisymmetric finite element model was established by ABAQUS to simulate the wheelset press-fitting process of a high-speed EMUs. The result shows that interference and friction coefficient is the key factor to ensure the assembly quality reach the standard;Besides, protruding assembly and oiling groove have significant influence on stress of contact position;appropriate shape error combination of wheel and axle is conducive to a correct press-fitting.
