连杆外延型曲柄摇杆机构的一种图谱分类法初探

A PRELIMINARY DIAGRAMS CLASSIFICATION OF THE EXTENDED ARM FOUR BAR MECHANISMS

本文在对连杆外延而形成工作臂的曲柄摇杆机构进行综合分析的基础上，着重对该类机构工作臂上工作点的运动特性进行了分析，揭示了机构工作点的运动变化与机构结构之间的内在联系，从而提出了该类机构的一种具有较强直观性、实用性、启发性和可比性的工作点运行轨迹图图谱分类法。

Based on synthetic analysis of the extended arm four bar mechanisms,kinemtic characteristic analysis is emphatically conducted for the function pathes of the working point of the mechanisms,It is the classfication of diagrams that reveals the internal relation between the diagrams and structures of the mechanisms,for it has the more on its practical,audiovisual,comparative and enlightening essence.
