摘　　要：采用ANSYS有限元分析软件对某200MW机组的某几级隔板进行线性分析,并与试验值和常规计算值进行比较,结果显示有限元分析与隔板挠度试验数据相吻合,表明此有限元分析法能准确计算隔板的挠度和应力。This paper used ANSYS finite element analysis software to carry on the linear analysis to some stage diaphragms of 200 MW turbine,and compares with experimental values and conventional calculation valves.The results show that the calculation with ANSYS software is consistent with experimental value,it indicates that the finite element method can calculate the deflection and stress of diaphragm accurately.
