英文摘要： The most important part of original mechanical system innovation is mechanism topological structure innovation, i.e. invention of new mechanisms. There have been establihsed three types of method for mechanism topological structure innovation up to now: screw theory based method, displacement subgroup base method and the Position and Orientation Characteristic (POC) based method. There still needs a breakthrough in automation of mechanism topological structure design. This project will focus on the geometrical method for topological structure design of parallel mechanisms based on POC. Basic principles and algorithms for computer aided topological structure design will be proposed. The main contents include: (1) geometrical representation of POC of mechanisms. (2) algorithm for basic topological equation operation and its implementation. (3) algorithm for topological structure analysis of parallel mechanisms and its implementation. (4) algorithm for topological structure synthesis of parallel mechanisms and its implementation.(5) performance assessment and optimal selection of mechanism topological structures based on POC and its physical meaning.(6) automation generation for topological structure design of 2-6 dof parallel/hydrid automatic optoelectronic product testing platforms and optimization prototype implementation. This project will lay a solid foundation for development of proprietory topological structure design software and provide an effective tool for relevant design or research personnels.
