The spanning tree method of identifying isomorphism and topological symmetry to planar kinematic chain with multiple joint is presented. Directly using the kinematic-chain’s structural graph in the mechanism motion sketch or its inversion,the connected relations of components and joints can be presented through the spanning tree constructed by Depth-First traversal the graph and the distribution of back-edge. Then, whether two graph isomorphism and components’topological symmertry can be identified through comparing the structural characteristic of spanning tree and the distribution characteristic of back-edge. The study shows that the method is effective, directly perceptible, simple and convenient, and easily dealt with by computer.
