摘　　要：针对平面机构运动链的特点,在研究了其结构不变量的基础上,基于杆件环路代码提出了新的运动链结构恒量,该恒量将杆件的级别、运动副数目以及各杆件的连接关系考虑在内。据此提出了利用该恒量对运动链进行同构识别的方法,该方法具有高效可靠、应用简便等特点。Aiming at the characteristics of planar kinematic chains, the paper presents a new structure constant link code of a kinematic chain on the Dasis of studying its structural invariants. The proposed structure constant takes into aeount of the degrees of links, the numbers of kinematic pairs and the connecting relation of links in kinematic chains. Hence then a method of isomorphism identification of kinematic chains is proposed by the constant. The method is tested by examples and has been proved of high efficiency and sood reliability.
