摘要
工程上广泛使用二维木模图为依据来表达叶轮模型。提出了沿等高线方向和沿轴截面方向给定的线型两种方法,实现水泵叶轮扭曲叶片及叶轮的参数化实体造型。在叶轮扭曲叶片参数化实体造型中对所求曲线、曲面的光顺方法进行了探讨,使扭曲叶片的造型更加准确、光滑,为进行叶轮流动性分析、数控加工模具等提供了良好的模型基础。
According to the extensive application in which 2D drawing is used to devise the model ofcentrifugal pump blade of impeller, the paper puts forward two kinds of method to draw 3D solid molde of pumpimpeller. In addition more attention has been paid to the study of smoothness of curve and surface. As a resultit supplies a good model for further study on CFD and NC.
