摘　　要：灯泡贯流式水轮机在水电站广泛使用,座环是水轮机的关键部件之一,承受机组的大部分载荷,必须有足够的强度、刚度及动态性能。采用Pro/E软件建立某型水轮机座环的三维模型,基于ANSYS Workbench有限元软件进行静力学及模态分析,获得了最大水流工况下座环的静态受力特性及模态特性,仿真分析结果为水轮机座环及整机优化设计提供科学依据。Stay ring is one of the critical part in bulb tubular turbine which is widely used in hydroelectric power, which should have enough strength, stiffness and dynamic property as supporting the most of weight of the turbine set. The 3D model of stay ring of bulb tubular turbine is built by Pro/E software.The stress characteristics and modal characteristics of stay ring at the maximum hydraulic load is obtained based on static analysis and modal analysis proceed by ANSYS Workbench software. The result provides guidelines for the optimization design of stay ring and the whole bulb tubular turbine.
