摘　　要：大型混流式水轮机在轮叶片结构的动力特性十分特殊。尤其是在水轮机叶片的动力结构体系上,需要根据混流式水轮机的整体情况对其受力结构以及动力情况进行较为明确的分析。同时,还要根据其叶片的动力变化情况,根据其旋转特点以及动力变化体系的特点。在多流向以及混流式的变化情况下,其叶片的结构动力也会根据水轮机的变化而发生相应的改变。本文主要针对大型混流式水轮机转轮叶片结构的动力特性进行分析,并根据其力的变化性,对叶片结构的多维变化进行分析。The dynamic characteristics of runner blade structure of large Francis turbine are very special.Especially in the dynamic structure system of the turbine blade,it is necessary to make a clear analysis of the force structure and the dynamic situation according to the overall situation of the Francis turbine.At the same time,it should analyze according to the dynamic changes of its blades and the characteristics of its rotation and the dynamic change system.In the case of multi-flow direction and mixed flow changes,the structural power of its blades will also change correspondingly according to the changes of the hydraulic turbine.This paper mainly analyzes the dynamic characteristics of the runner blade structure of large Francis turbine,and the multi-dimensional change of the blade structure according to the variability of its force.
