摘　　要：机构自由度计算是机构分析的最基本问题,为清晰准确分析机构输入、输出运动能力特性的构成、转化、综合等关系和过程,科学合理重新定义运动维度表象数、机构输入自由度、机构输出自由度等概念,给出3类副运动基对RR、RP、PP。结果表明,机构只存在一阶输出副运动,以实例证明机构不存在二阶及更高阶输出副运动。The calculation of mechanism degrees of freedom is the most basic problem of mechanism analysis.in order to clearly and accurately analyze the relationship and process of composition,transformation and synthesis of mechanism input and output motion capability characteristics,the concepts of motion dimensional representation number,mechanism input degrees of freedom and mechanism output degrees of freedom are scientifically and rationally redefined,and three types of paramotor base pairs RR,RP and PP are given.the results show that only first-order output paramotor is found to exist in the mechanism,with It is proved empirically that the mechanism does not have second-order and higher-order output paramotions.
