Automatic Synthesis Of Planar Kinematic Chains With Single Multiple Joint Based On Vertex Symmetry Detection

With the continuous development of technology and the progress of innovativemechanism design, machinery manufacturing is dominant in ever-bigger industries.Nowadays, the existing simple bodies have been unable to meet the broad requirements ofvarious fields, which makes us have to design a full range of integrated system to achievein-depth study of complex mechanism graphics. The planar multiple joint kinematic chainis one of the important research mechanisms. However, the mechanisms of the multiplejoint kinematic chain are more complex relative to the planar simple joint kinematic chain,the models are relatively independent, and so far neither integrated approach nor existingtheory of the simple joint kinematic chain has been embedded in the planar simple jointkinematic chain.In response to this situation, based on the vertex symmetry detection, this paperintroduces the methods and developes a corresponding set of integrated software for singlemultiple joint kinematic chain, analyses and optimizes mechanism types, which play animportant research role in autonomy innovative mechanism design, achieve to select thetypes for important machineries.Firstly, this paper briefly describes basic knowledge of mechanism and graph theory,the definition of the adjacency matrix, isomorphic detection, rigid sub-chain detection, andthe new two-color topology graph of the multiple joint kinematic chain. It plays animportant role in single multiple joint kinematic chain synthesis and computer-aided.Secondly, in accordance with the conversion between the single joint and the multiplejoint kinematic chains, a path-based search method of the vertex symmetry detection ispresented, this method can eliminates the isomorphism types of multiple joint kinematicchains; the detection method of rigid sub-chain also can eliminates the rigid body types.This paper is based on Visual C++6.0visualization programming environment, developesa human-computer interaction interface.Finally, based on the above interface, the mechanism kinematic chain topology typesare different from each other, according to the specific requirements of the mechanical design task, with the help of the AutoCAD software, we can quickly and easily optimizeand screen out the diagrams about the kinematic chains; with the SolidWorks we can drawthe mechanism schematic diagram to a three-dimensional model and then make thesimulation test.
