平面连杆曲线的分布规律及其曲线绘制的一种简捷方法

Study on Distribution Law and Simple Drawing Method for Planar Link Curves

基于平面四杆机构的连杆对机架作平面运动的一对瞬心线，研究了连杆平面的运动及连杆曲线的形成情况，从而给出了平面四杆机构的连杆曲线形状变化及其类型分布的规律，并提出一种绘制连杆曲线的简捷方法。

Based on moving and fixed centrodes of the relative motion between link and fixed link for planar linkage, this paper studies the motion of planar link and forms of its link curves.The shape change and the distribution law of its curve type are gived.A simple and direct drawing method for planar link curves is presented.
