介绍了传统经验公式Wahl法和目前普遍采用的有限元数值计算方法，指出在对汽轮机隔板强度进行有限元计算时，设定合理准确的边界条件至关重要。通过对某汽轮机厂的实际隔板模型进行计算对比，表明在处理隔板的支承情况时，采用接触分析有限元法能更准确地计算隔板体的挠度和应力。

As the steam turbines develop to the direction of large capacity and high parameter ,the reliability of steam turbine diaphragms is increasingly drawing attention .This paper has a brief introduction to Wahl method and numerical computation method usually used at present .In the procedure of calculating steam turbine diaphragm ’ s strength,defining reasonable boundary conditions is very important according to the real working status .An actual diaphragm model from one Turbine Works is analyzed in this paper , proving that contact FEM , used to simulate its supporting conditions , can obtain more precise deflection and stress results of the diaphragm body .
