摘　　要：对混流式水轮机中的转轮叶片进行了实体建模研究。从叶片木模图提供的数据出发,在UG软件平台上进行曲面拟合处理,并采用NURBS方法对混流式水轮机叶片进行几何造型,给叶片精密加工提供了数字化模型,为叶片加工精度和加工质量奠定了基础。In this paper the modeling method of Francis turbine blade is researched.Based on UG and the data on original wooden patterns,curved surface fitting was conducted and geometric modeling of Francis turbine blade was established by NURBS,which provide a digital model for precision finishing of a turbine blade,thus laying the foundation of ensuring accuracy and quality of blade machining.
