DOI: 10.1016/j.mechmachtheory.2019.103740
Abstract: Abstract For mechanism design, the isomorphic kinematic chains (KCs) should be deleted to improve design efficiency. At present, most methods of isomorphism detection involve complex concepts and comparison of intermediate parameters. Moreover, when the number… read more here.
