摘　　要：叶轮是泵重要的传递动力部件,为了提高其水力效率,往往将叶片设计成复杂的扭曲形状。现在对于叶轮的三维建模都是从已设计好的二维木模图上获取点坐标,导入三维软件中,以点线面的方式构造。在以往叶片曲面的实体建模中,多是将叶片表面的型线直接混合,不利于对曲面的修整。进入Pro/E特定的造型环境下,可以方便地利用各种针对曲线和曲面的分析编辑工具,实现对曲面光顺的有效控制,从而使设计出的叶片表面光顺,满足后续流体分析和数控制造的要求。Impeller is an important component in a pump for power transmission.To improve its hydraulic efficiency,the blade usually is designed into a complex and distorted shape.When the data of wooden patterns are imported into Pro/E,several blade curves are established and then space surface is constructed.Since the devisers always sweep and blend blade curves into surface immediately,it goes against the modification of surfaces.Under the specific modeling circumstances of Pro/E,various tools can be conveniently used to analyze and edit curves and surfaces,so that smooth surface can be built and the further study on CFD and NC would go well.
