摘　　要：用Pro/E建立压气机叶轮轴-毂三维模型,利用ANSYS软件采用子结构结合网格随移技术的分析方法,建立其有限元模型。采用虚拟正交试验方法对压气机叶轮轴-毂进行仿真,得出过盈量、摩擦系数、转速对最大单位摩擦功和平均摩擦功影响显著性次序及影响规律,得到最优组合。结果表明,模拟及正交试验优化结果准确、可靠,有效地降低了摩擦磨损程度,对实际装配过程具有一定的指导作用。A three-dimensional model of a compressor impeller is set up by Pro/E. Based on the ANSYS, the finite element model is established by using the analysis method of combining submodle and Para Mesh. The compressor impeller spindle-hub is simulated by virtual orthogonal design optimization method. The influence significance order and laws of interference, friction coefficient and rotation speed on the maximum unit friction work and average friction work, and the optimized parameters are obtained. The verifying experiment shows that the results of the numerical simulation and orthogonal experiment are accurate and reliable, and the friction and wear is effectively reduced, and certain guiding references to actual assembly process are got.
