摘　　要：瞬心法分析平面机构的运动简单而又适用 ,但平面机构的速度瞬心由于受到多方面的限制而难以精确求解。介绍一种利用AutoCAD精确图解平面机构速度瞬心的三三分组法 。It is simple and applicable to analyse the motion of plane mechanism with instant center.But it is difficult to seek the accurate solution for the instant centers of the plane mechanism because some limiting conditions.This paper introduces the method of division by three for finding the instant centers of plane mechanism with AutoCAD and shows its application in an example.

关 键 词：刚体 相对运动 瞬心 三三分组法
