摘　　要：本文以现有的汽轮机零部件安全性的设计校核方法为基础，提出了汽轮机关键零部件可靠性的设计方法。文中介绍了汽轮机零部件设计量分布参数的确定方法和静强度、疲劳强度及振动的可靠性计算模型，并给出了汽轮机叶片、隔板、叶轮、转子和轴承的可靠性设计方法及应用实例。Abstract This paper presents a reliability design method for major components of steam turbines,based on prement-day safety design methods for steam turbinecomponents.Methods for determening the distribution parameters of designmagnitudes are given together with reliability calculation models for staticand fatigue strength as well as for vibration calculations. Reliability designmethods of blades,diaphragms,bladed discs,rotors and bearings are elucidatedaccompanied by some practical examples.
