摘　　要：讨论了纯刚体机构的局限性 ,并由此导出了广义机构 :广义机构是实现可控运动或不可控运动的驱动元件与由刚性、非刚性构件组成的运动链二者的集成体 ;指出广义机构具有多元性、输出运动多样化、运动具有可控性等特征 ;从研究对象、研究内容以及一些概念方面详细讨论了广义机构与狭义机构的差别 ,提出了广义机构的运动学和动力学分析与综合等问题。The limitation of rigid mechanisms is discussed in detail in the paper, and the definition of generalized mechanisms results from this: a generalized mechanism is the integration of driving elements controllable un-controllable and motion chain composed by rigid and/or non-rigid components. It's regarded that generalized mechanisms are characterized with multi-components, output motion variation and controllability and so on. And the difference of generalized mechanisms from rigid mechanisms is discussed in detail according to research objects, research content and some concepts. Put forward some questions on generalized mechanisms' kinematics and dynamics' analysis and synthesis.
