摘要
运用UG/Grip技术对低比转速叶轮进行三维造型设计,获得了一种先进的低比转速叶轮参数化设计方法,从而能够及时、直观地考察叶片的水力特性和机械特性。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,有利于提高叶轮设计质量。
In this paper, an advanced method of parameterized design for low specific speed impeller was established during the procedure of the 3D design of a low specific speed blade by means of UG/Open Grip technique. This method can make the check of the hydraulical and mechanical design qualities of the blades quicker and easier. At the same time, the parameters may be modified in manner of the interactive operation. It had strengthened the interactive design function of the CAD system. The method is plastically useful for improving the design quality of impellers.
