英文摘要： Flexible metamorphic mechanism (FMM) has been introduced to engineering and technology domain with special and important applications. In this program, the problem of dynamics design in flexible metamorphic mechanism is proposed for the first time and an in-depth research will be done subsequently. A new nonlinear dynamic equation of FMM which can be used to achieve rapid conversion of any two configurations is established firstly. The evaluation system of dynamic global performance index of FMM is proposed and established. And furthermore, the establishment of dynamics optimization design model in FMM is achieved. The main contents can be listed as follows: research on dynamic behaviors of FMM in congfiguration change, the establishment of nonlinear dynamic equation of FMM, the establishment of evaluation system of dynamic global performance index in FMM, research on the theory and method of dynamics optimization design in FMM, manufacture and experiment study on dynamic performance aiming at two real flexible metamorphic mechanisms. Comprehensive and systemic theories and methods of dynamics design in FMM which can enrich and develop the mechanics and dynamics will be formulated in this program. And meanwhile, important theories and experimental basis will be provided for the design and engineering applicatio
