计算机绘制连杆运动轨迹图谱的方法

The study to improve the method of drawing the atlas of connecting rod motion track

本文推导出了四杆机构中连杆上任意一点的坐标方程,用常用的应用软件Excel计算出该点在运动过程中的一系列坐标值,并采用Excel中的“插入图表”功能自动绘出了连杆运动轨迹图谱,为设计者在按连杆运动轨迹设计四杆机构时提供了一个准确、简捷且非常实用的工具。

In the paper, the author deduces the equation of a random point on the connecting rod of the four-pole machine, and computes a serials of coordinates in the point's motion by using the Application Software, that is Excel. Then draws the atlas of the connecting rod motion track automatically by adopting the function of Insert diagram in Excel. Thus, it gives us an exact and applied tool to design four-pole machines according to the connecting rod's motion track.
