摘　　要：过盈连接大量应用于齿轮等与轴类的连接中,所以过盈配合状态的精密分析非常重要。介绍了使用三维建模软件Pro/E及其有限元分析模块Pro/MECHANICA对过盈配合进行精密三维仿真分析的方法。通过对轴与厚壁圆筒过盈配合进行有限元分析与理论计算结果的对比,表明有限元与理论计算结果相吻合,而且在接触边缘处有限元分析结果可以精确仿真出应力集中现象,更加符合实际。同时分析了离心力对过盈配合的影响,给出了一些有益的结论。The state analysis of interference fits in connection with shaft and gears, is more important. Based on the soft Pro/E and Pro/MECHANIA, the accurate calculated method of interference fits is introduced. The result compared with the FEA values and numerical ones about the interference fits of axis and thick - walled cylinders indicates the FEA is close in numerical ones, stress concentration accurately. And and in the edges of the interference fits, the FEA can simulate the phenomenon of some useful results are obtained about centrifugal force in interference fits.
