Creative Design of the Sewing Machine's Feeding Mechanism Based on Topological Characteristics of Kinematic Chains

摘要

If we choose one original mechanism as the object of study, treat it abstractly, and induce the topological properties of this mechanism, we can get basic chain of original mechanism. With the tool of graph theory, we can list the map of the kinematic chains based on the original mechanism in accordance with certain procedures. In doing so we can prevent the missing phenomenon or the isomorphic phenomenan. Then through the redistribution of the frame, orginal driving link and rod group, we can get a series of new mechanism which has a better performance.
