摘　　要：通过有限元分析软件ABAQUS数值模拟了轮对注油压装过程,对比分析了不同过盈量下以及不同热处理工艺下的压装力,研究了不同过盈下,车轴经调质和表面淬火处理后,在含有注油压装过程与无注油压装过程的接触应力和轴向正应力变化规律,得出了一些有意义的结论。According to the finite element software ABAQUS,the paper undertakes the simulation of the pressing process of the oil-injecting,has the comparative analysis of the pressing stress under the various magnitudes of interference and heat treatments,researches the contact stress in the pressing process with the oil-interjection and the pressing process without the oil-interjection after the tempering and surface hardening treatment with various interference magnitudes as well as the law for the axial direction positive stress changes,and has some valuable conclusion.

关 键 词：注油压装 过盈量 车辙 微动疲劳
