摘　　要：运用UG/GRIP技术对叶轮的轴面流道进行参数化造型及校核,获得了一种先进的叶轮轴面流道参数化设计方法,从而能够及时、直观地考察叶片的工作特性。同时可采用交互方式对叶轮设计参数进行修改,增强了叶轮计算机辅助设计系统的交互设计能力,有利于提高叶轮的设计质量。该方法不仅适用于泵的叶轮,对于涡轮及压气机的叶轮等也同样适用。In this paper, an advanced method of parameterized design for an axis flow-path of a impeller is established during the procedure of the modeling and checking of an axis flow-path by means of UG/GRIP technology. This method will assist designers to check the aerodynamic qualities of the impeller immediately and directly. At the same time, the parameters can be modified in man- ner of the interactive operation. It will strengthen the interactive design function of the CAD system. The method is practically useful for improving the design quality of impeller. This method also can be used in the design of the turbine and compressor.
