Abstract:
The digit weighted simplified graph and corresponding matrix and
code for the representation of the topological structure of kinematic
chains are given in this paper. A new parameter called incident which
can describe the topological characteristics of the vertexes in a
weighted graph is first introduced to distinguish different types of
vertexes in the graph. Then the incident degree code of a kinematic
chain can be obtained, which is one-to-one corresponding to the
topological structure. The identification of isomorphism for kinematic
chains can be correctly and efficiently performed using the method
presented in this paper.
