四杆机构位移分析及连杆曲线绘制

Displacement Analysis and Coupler Curve Drawing of 4-bar Linkage

对于四杆机构的位移分析，文献中缺少统一规范的计算方法，这给四杆机构的分析和利用带来了不便。为便于计算机编程计算，给出一种简便规范的四杆机构位移分析的方法──位置解法。讨论连杆曲线的计算机绘制，并给出程序框图及连杆曲线绘制的一个实例，为更好地了解和利用四杆机构的运动规律，提供了一套有效的计算方法。

A simple and convenient displacement analyzing algorithm for 4-bar linkage is proposed, and the relevant coupler curve drawing is also discussed in this paper. This method is characterized in making full use of the law of motion for the 4-bar linkage. An example of coupler curve drawing is presented.
