摘　　要：针对过盈压装技术,特别是对花键轴压装工艺进行了研究。从理论上推导了花键轴的压装过程,建立了压装力计算公式;采用Deform有限元软件进行了仿真分析,得到了应力、应变分布和压装力变化曲线;通过实验法,得到实际的压装力-位移曲线。压装力结果表明:理论计算、有限元计算与实际压装基本一致,可为花键轴的压装工艺提供一定的理论参考。In this paper,the processing technology of interference press-fit is studied,especially the press-fit about the spline shaft. Firstly,the press fitting process of the spline shaft is deuced theoretically,and the calculation format of the press fitting force is established; Secondly,the variation curves of stress,strain distribution and the fitting force are obtained through simulation analysis on the press fitting process of the spline shaft by the Deform finite element analysis software; Finally,the actual fitting force-displacement curve is obtained through experiments. The results about the press fitting force show that the theoretical calculation,finite element calculation and the actually press-fit are basically consistent. It could provide the basis for establishing the press fitting process of the spline shaft.
