并联机构拓扑结构的字符串描述及其应用

Description of Topological Structure of Parallel Mechanisms and Its Applications

在研究并联机构拓扑结构的基础上,提出一种新的并联构型字符串描述方法,对并联机构的支链结构、平台外形、链接方式等进行抽象描述,为并联机床构型设计数字化过程中的并联机构构型的选择、建模、综合等提供并联机构拓扑结构完备、简洁、直观的描述字符串,从而为相关的应用程序间以及人机交互提供数据交互的标准。讨论了这种描述方法在PMT-VPDS中的具体应用。

Based on the topological structure of paral-lel mechanisms, a method of describing parallel architec-tures in character strings is presented. The characterstring description of parallel architectures can describe ab-stractly the chain structures, platform structures, jointsand drivers of the parallel mechanisms. The method canmeet the needs of digitized design of parallel machinetools, and the strings can be used in the system of paral-lel architecture digitized design. The strings should be asthe data intercommunication standard between user andsystem, and be used in programs of architectures selec-tion, modeling, architecture synthesizing, etc.. The ap-plications in PMT-VPDS of this description method arediscussed in details.
