The system group classification is central to the kinematic structure and consists of determining a sequence of kinematically and statically independent-simple chains which represent a modular basis for the kinematics and force analysis of the mechanism. This article presents a novel graph-based algorithm for structural analysis of planar mechanisms with closed-loop kinematic structure which determines a sequence of modules (Assur groups) representing the topology of the mechanism. The computational complexity analysis and proof of correctness of the implemented algorithm are provided. A case study is presented to illustrate the results of the devised method.enginfo:eu-repo/semantics/closedAccessinfo:eu-repo/semantics/articleGraphKinematic structureAssur groupStructural analysisSystem group classificationGraphKinematic structureAssur groupStructural analysisSystem group classificationAcceso cerrado2016-09-26Durango, SebastianCorrea, JorgeRuiz Salguero, Oscar10.1007/s11012-016-0403-5
