摘　　要：混流式水轮机因其叶片为空间扭曲形态,三维实体建模较为困难,利用PRO/E与AutoCAD相结合,以Auto CAD中的叶片平面木模图为基础,利用PRO/E建模软件中的三维功能,采用导入点数据文件形成叶片各横截面,面实体化形成叶片三维体的方法建出叶片实体。通过使用PRO/E中旋转切割功能对进水边、出水边、上冠及下环各部位进行曲面光滑处理,构建出更加满足水力要求的转轮三维空间型面,从而可准确得到由平面图到三维体所表达的转轮实体。Due to the spatial distortion of the blades of a mixed flow turbine,3D solid modeling is difficult.By combining PRO/E with AutoCAD,based on the blade plane wood model in Auto CAD,and utilizing the 3D function in PRO/E modeling software,the blade cross-sections are formed by importing point data files,and the blade solid is formed by surface solidization.By using the rotation cutting function in PRO/E to smooth the surfaces of the inlet,outlet,upper crown,and lower ring parts,a three-dimensional spatial surface of the impeller that better meets hydraulic requirements can be constructed,so that the runner entity expressed from the plan to the three-dimensional body can be accurately obtained.
