摘　　要：对某大型离心鼓风机叶轮结构强度在改进前后进行了有限元分析。结果表明:通过优化叶轮叶片在轮盘上的倾斜角度,大幅降低了叶轮内的最大变形量和最大离心应力,满足了叶轮材料刚度和强度要求,使叶轮安全性得到了提高。The strength of a large centrifugal blower impeller is investigated with finite element analysis before and after improvement. It is indicated that through optimizing the lean angle of blades on wheel disc, the maximal centrifugal stress and the maximum deformation of the impeller is decreased greatly and meets the requirements of strength and stiffness of the impeller material. So the impeller strength safety is increased.
