计算机辅助运动分析与绘图

COMPUTER AIDED ANALYSIS FOR THE MOTION OF MECHANISM

本文运用约束方程法对平面机构的运动提出了五种模块,并列出其数学模型。利用AUTOCAD提供的命令组文件的概念,用高级语言编制了能被AUTOCAD调用的绘图文件。最后以六杆机构,齿轮—连杆机构,凸轮—连杆机构为例,说明对平面机构的轨迹进行模块式组合设计与绘图的方法及计算机运算框图。

The paper presents five modules for kinematics of planar mechanism by the con- strained equation method and gives their mathematical models.In accordance with the concept of script file on AUTOCAD software,the graphic program called by AUTOCAD software is compiled in High-level language.Finally,by the examples in“six-linkes mecha- nism”,“gear-and-connecting rod mechanism”,“cam-and-connecting rod mechanism”,the component module method to design and to draw paths of planar mechanism is explained and programming chart is given.
