摘　　要：在运动链型综合过程中,运动链的同构判定是重要且复杂的问题之一。提出了一种基于构件-构件邻接矩阵的改进Hamming数同构判定新方法。针对运动链中复合铰链难以分析和识别问题,提出了一种构件-构件邻接矩阵的含有复铰运动链描述方法。该矩阵包含运动链的拓扑结构信息,具有描述的唯一性。定义改进Hamming数原理,并采用提出的改进Hamming数新方法对运动链进行同构判定。案例证明了该新方法的准确性和高效性。In the synthesis process of kinematic chain,the isomorphism determination of kinematic chain is an important and complicated problem.A new method to improve Hamming number isomorphism determination based on link-link adjacency matrix is proposed.In view of the difficulty in analysis and identification of multiple joint in kinematic chain,a link-link adjacency matrix description method of kinematic chains with multiple joints is proposed.This matrix contains the topological structure information of the kinematic chain and is unique in description.Then,the principle of improve Hamming number is defined,and the proposed new method of improve Hamming number is adopted to identify isomorphism of the kinematic chain with with multiple joints.Finally,the case proves the accuracy and efficiency of the new method.
