摘　　要：利用响应面法设计仿真试验,研究动压马达转子体锥配连接结构3个因素(锥配斜度系数、锥配过盈量、薄壁厚度)对2个指标(球碗变形、锥配效果)的影响大小。通过因素影响力分析及响应面分析,得到各因素指标之间关系,并据此给出较优的转子体结构参数:薄壁厚度1.2mm、锥配斜度系数250、锥配过盈量3.9μm,对应球碗变形量0.122μm、锥配预紧力377.1N,即满足了球碗变形较小、锥配预紧力较大的多目标优化需要。The response surface method was used to design the simulation test to study the influence of three factors(taper fit angle coefficient, taper fit interference, thin wall thickness) on the two indexes(ball bowl deformation and cone fit effect) in the taper connection structure of the rotor body of the dynamic pressure motor. Through the factor influence analysis and response surface analysis, the relationship between each factor index is obtained. The optimal structural parameters of rotor body are given: the thin wall thickness is 1.2 mm, the taper fit angle coefficient is 250, the taper fit interference is 3.9μm, the corresponding deformation of ball bowl is 0.122μm and the preloading force of cone configuration is 377.1 N, that meet the needs of multi-objective optimization with smaller deformation of ball bowl and large preload of cone.
