摘　　要：本文介绍了汽轮机隔板刚度的可靠性设计方法。该方法把隔板挠度和汽轮机通流部分轴向间隙按照实际情况处理为随机变量,通过实测数据的统计和数值计算确定有关随机变量的分布参数,并使用概率设计法确定隔板刚度设计的可靠性指标。文中给出了应用实例。This .paper describes one stiffness reliability design method of steam turbine diaphragms. The method considers the deflection of diaphragms and the axial'clearance of turbine flow path as random variables according to actual condition. The distribution parameters of the random variables are determined through the statistics of test data and the numerical calculation. The reliability inderes for stiffness design of diaphragms are estimated by the means of probabilistic design. A diaphragms reliability design exsign example is given.
