摘　　要：针对工业应用中的一类并联机构——3T2R并联机构,提出了基于G_F集构型理论的并联机构型综合方法,给出了3T2R并联机构的构型综合的具体步骤。结合具体3T2R并联机构的应用参数需求,最终筛选出部分具有确定末端运动特征的3T2R并联机构。从中选出3-PPPR1R2为研究对象,运用ADAMS对该机构进行了运动学和动力学分析,验证了基于G_F集构型理论的并联机构型综合所选3T2R并联机构的正确性。Aiming at a kind of 3T2R parallel mechanism used in the industrial application, the method of parallel mechanism type synthesis based on Gr set configuration theory is proposed, the specific steps of the 3T2R parallel mechanism type synthesis are given. Combining with the specific parameter, the final selection of 3T2R parallel mechanism with determined motion features is filtered. The 3 - PPPR1R2 is selected as the research object, the kinematics and dynamics analysis of the mechanism is carried out by using ADAMS, and the correctness of the 3T2R parallel mechanism based on the theory of GF set configuration in parallel mechanism is verified.
