摘要：
The development of productivity and the innovation of engineering technology required mechanisms to have the multi-function of self-reorganization and reconfiguration to meet the needs of complex working conditions. Reconfigurable mechanisms had variable mobility and varying configurations to meet the requirements of multiple tasks, multiple working conditions and multiple functions. However, the research history of mechanism evolution and furcation principle, which determined the design method, was still not fully understood by scholars. Herein, from the point of view of the evolution and furcation principle of metamorphic mechanisms, based on screw theory, Lie group, Lie algebra and differential manifold, the mechanism evolution and the interrelationship between the mechanism motions and the constraint spaces were revealed. Then, the furcation principle and the controllable singularity configuration in the evolution of the mechanism were explored. Moreover, the historical relationship between metamorphic mechanisms, origami mechanisms and deployable mechanisms was discussed, and the configuration design, performance synthesis, new design concept of metamorphic mechanisms and their innovative application were reviewed. © 2020, China Mechanical Engineering Magazine Office.
