针对本课题所设计的斜流式水轮机转轮叶片进行受力分析并计算其合成力的的大小,应用UG建立了其叶片的实体模型,将其导入ANSYS有限元分析软件,进行应力和变形分析,根据分析结果进行强度校核,结果证明该斜流式水轮机叶片满足材料的强度要求,最后提出了减小应力集中的改进意见,并为今后的设计提供科学依据。

This paper is based on the quasi-3D flow theory to study the design method of runner blades of inclined flow turbine and to deduce the formula(the S1 and S2 m relative flow surface formula) that is more applicable for the inclined flow turbine runner and establishes the finite model by the finite method.
