【Abstract】 A new type of mechanism, which changes its con-figuration and subsequently its mobility during motion, is dis-cussed. Based on the mathematical description of the configu-ration changes, a set of matrix operations in the configuration changes are utilised, and a method in synthesising a metamor-phic mechanism is proposed. From a final structure of the mechanism with its corresponding adjacency matrix, different combinations of links are investigated. The structure synthesis with link addition is then related to the binary operations in the corresponding matrix transformation, which presents the change of corresponding configurations. New mechanisms are then produced and the isomorphism is used to reduce the num-ber of optional results.更多还原
