摘　　要：运用ANSYS软件对某大型轴流式水轮机顶盖进行刚强度及动态特性分析表明,原结构存在严重的结构问题,同时动态特性较差存在引起共振的可能。提出的改进方案具有更好的刚强度性能及动态特性,满足刚强度及动态特性设计要求。The results of strength and dynamic characteristics analyses for head cover of a large axial flow turbine show that the original structure has serious structural problems and poor dynamic characteristics,so that the resonance is most likely to occur.Proposed improvement scheme has better strength performance and dynamic characteristics,and it meets strength and dynamic characteristics of the design requirements.
