摘要
同构识别在机构类型综合中占有重要位置。本文在对含高副平面运动链分析的基础上，提出了含高副平面运动链支路码的概念，并提出了一种用计算机对含高副和不含高副的平面运动链均适用的同构识别方法。该方法不受运动链杆数和自由度数的限制，且速度快、计算量少。经大量实例计算。
The identification of isomorphism occupies an important place in the structural synthesis of planar mechanisms. Based on analysis of the planar kinematic chains with higher pairs ,this paper presents the concept of path code of planar kinematic chains with higher pairs and an algorithm for the identification of isomorphism.The algorithm is suitable for planar kinematic chains with and without higher pairs.The algorithm would nor be confined by the number of links,the degrees of freedom and the number of higher pairs ,and will take a high speed of identification.Testified by a lot of examples,the algorithm is practically effective.
