Automatic Synthesis Of Fractionated Structure Kinematic Chains Based On Atlas Database Of Closed-loop Kinematic Chains

Recently, the study of the structural of mechanisms has made tremendous progress.As a result, a large number of various links and degrees-of-freedom (DOFs) weresynthesized, which made the study of structural synthesized of mechanisms andoptimization a revolutionary change. However, with the development of moderntechnology, the existing varied of simple mechanisms can not meet the designrequirements. This forces us to study structural synthesized approach of mechanisms thatwith a complex structure. The mechanisms which are with fractionated structure are veryimportant. For example, it has been widely applied in the field of aerospace field, thecomplex field of robotics, as well as large engineering machinery. But these structuralsynthesized of mechanisms focused very little attention on fractionated kinematic chain.So studying the theory of structural synthesized of fractionated kinematic chain anddeveloping corresponding software is very important for creative design of mechanisms.Firstly this paper introduces the basic terms and concepts of topographical synthesisof mechanisms kinematic chains graph, topological graphs, as well as its matrixrepresentation. Then briefly introduces fractionated kinematic chain theory and the basicconcepts of graph theory, proposing a new topological vertex symmetry discriminationalgorithm. Based on the atlas database of closed-loop kinematic chain, and use thetopology of vertex symmetry algorithm. At last a program based on Visual C++ isaccomplished to realize the computerization for the structural synthesized of fractionatedkinematic chain.Using of the planar fractionated kinematic chain and the topology of vertexsymmetry discrimination algorithm, A method of synthesis the planar fractionatedkinematic chain, base on the atlas database of closed-loop kinematic chain, This synthesismethod will not distinguish complex isomorphic.Then, based on the atlas database ofclosed-loop kinematic chain, a program which is used to structural synthesized of theplanar fractionated kinematic chain is accomplished base on Visual C++ 6.0.
