对平面机构运动链结构组成进行探讨后,研究了运动链中的结构不变量,并基于缩杆邻接矩阵提出了4个新的运动链结构恒量序列,这些恒量序列将杆的级别、运动副数目以及各杆的连接关系考虑在内。以此为基础,提出了对运动链进行同构识别的距离和序列法。该方法实质上是对运动链进行分类同构识别,因此具有操作简单、可靠性好、识别效率高等特点,已成功应用于12杆以下机构运动链型综合时的同构识别。
After discussing the structure of the kinematic chain of plane mechanism, the structural invariants in the kinematic chain are studied, and four new constant sequences of the kinematic chain structure are proposed based on the contiguous matrix of the squeezed rod. These constant sequences associate the level of the rod, As well as the connection between the rod into account. Based on this, the distance and sequence method of isomorphic identification of the kinematic chain is proposed. The method is essentially a classification and isomorphic identification of the kinematic chain, so it has the advantages of simple operation, good reliability and high recognition efficiency, and has been successfully applied to the isomorphic identification of kinematic chain synthesis under 12 bars.
