离心压气机叶轮一种消隐图形绘制方法

A Computer Aided Drawing Method with Hidden Line Elimiration for Centrifugal Compressor Impeller

本文给出了一种以微型计算机为工具绘制离心压气机叶轮图形的方法。针对压气机叶轮几何形状比较复杂的特点,提出了一种消除隐藏线的办法,可方便快速地得到消除隐藏线的叶轮轴测投影图等图形。例题表明这个方法是正确的成功的。为离心压气机叶轮计算机辅助设计提供了新的软件。对其他几何形状比较复杂物体的消隐图形绘制和计算机辅助几何设计也具有一定的参考价值。

This paper gives a method for drawing centrifugal compressor impeller by use of microcomputer. By eliminating hidden lines this method is conveniently and reapidly applicable to making the axonometric drawing of the impeller. Exemplary drawings show that the method is correct and feasible. A new software was devised for the CAD of centrifugal compressor impeller and is helpful to the drawing with hidden line elimination and the CAGD of other bodies with complex configuration.
