摘　　要：根据某涡旋压缩机虚拟样机曲轴实际工作载荷及位移边界条件,基于ANSYS Workbench平台建立有限元模型,对其进行应力和变形分析。并在此基础上利用DOE优化算法对曲轴-轴承结构进行多参数优化设计,从而减小曲轴的应力和位移变形,提高曲轴的径向刚度,为涡旋压缩机的结构设计和动力学研究提供参考。A finite element model based on ANSYS Workbench platform was established in reference of the actual work load and displacement boundary condition of the crankshaft in a virtual prototype of the scroll compressor to analyze its stress and deformation. And on this basis, DOE optimistic algorithm was used for optimum multi-parameter design of the crankshaft-bearing structure in order to reduce the stress and displacement of the crankshaft due to deformation and improve the radial stiffness of the crankshaft in an attempt to provide reference for structural design of the scroll compressor and for examination of its dynamics.
