机构组合方法的分类

Classification of Mechanism Composition

本文把机构的组合分为串行联接、并行联接、混合联接、封闭式联接、叠加联接组合方法 ,提出串行联接和并行联接中的基本机构是单自由度机构的概念以及用封闭式联接代替复合式联接和反馈式联接的观点。按其联接方式 ,把单自由度机构和多自由度机构的组合称为封闭式联接组合 ,使机构组合理论更加清晰、易懂 ,提高了机构组合方法的可操作性 。

The mechanism composition has been classified as series connection,parallel connection,series parallel connection,closed connection,stack connection,and feedback connection in this paper.It is emphasized that the primary mechanisms connected in series and parallel must be such mechanisms that have one degree of freedom only,the compound connection and feedback connection have been substituted by the closed connection.According to the connected patterns,the connection between mechanisms with one degree of freedom and multi degrees of freedom have been called the closed connection.Therefore it is quite clear to understand the theory of mechanism composition and it is easy to creat a new mechanism system when using this mechanism composition theorem.
