甲米一级混流式水轮机顶盖强度及刚度计算研究

Calculation and Research on Strength and Rigidity Calculation of Francis Turbine Cover for First Stage of Jiami Power Station

以甲米一级混流式水轮机顶盖为研究对象,应用ANSYS有限元分析软件,建立了顶盖的结构三维模型。根据水轮机的结构参数,对其结构进行受力分析与计算;施加受力后,分析了顶盖的应力与应变。计算表明其结构设计是可靠的,能充分保证整个水轮机的可靠性和寿命。

Based on research of head cover of first stage of Jiami Power Station francis turbine, 3-D model for head cover is established with ANSYS software. Analysis and calculation of the force for the structure of head cover are studied in accordance with structure parameters, then stress and strain of head cover are calculated in detail after exerting forces on head cover. Calculation shows that the structural design is reliable which can fully guarantee the reliability and life of the turbine.
