水轮机转轮的计算机辅助几何设计及图形系统

本文介绍在以长城系列微机为核心组成的,CAD工作站上开发的水轮机转轮的计算机辅助几何设计及图形处理系统(BLDCADG)。该系统是综合运用现代计算几何学,计算机图形学及现代水轮机转轮设计方法于水轮机设计制造中的成果,它还可用于其它具有复杂曲面零件的几何设计和图形处理。BLDCADG采用FORTRAN77语言设计,源程序序约350KB,以多级汉字菜单为人机交互界面。本系统已成为水轮机转轮设计制造中的一个有力工具,取得了明显的经济效益。

A SYSTEM OF COMPUTER AIDED GEOMETRIC DESIGN AND GRAPHICS PROCESS FOR HYDNAULIC RRNNER

In this paper, a system of Computer Aided Geometric Design and Graphics, process for Hydraulic Turbine Runner ( BLDCADG ) is introduced, which is developed on a CAD station that consists of " GRF.AT WALL " scries microcomputer and HP plouer and line printer We make use of modern computer geometries and computer graphics and recently developed design methods of hydraulic turbine runner in the system It can aslo be used for CADG and graphics process for other complex surfaces of machine parts- The described software is writled in FORTRAN77, which has about 350 KB of source code. The menu displayed in Chinese words have been used in the system as Man- Computer interface. BLDCADG has been provided its user as a powerful tool for design. and manufacturing of runner.
