平面三自由度连杆机构的型综合

Type Synthesis of Planar 3-Degree of Freedom Linkage Mechanism

利用图论理论,分析了平面三自由度的8杆、10杆机构类型的数综合。利用数综合的结果,从拓扑结构出发,分析研究了平面三自由度的8杆、10杆机构的运动链的基本结构型式。从机构的可运动性出发,得出了8杆机构运动链的全部5种型式,以及10杆机构运动链中表明多副杆件不同串、并联关系的40种基本机构型式。为平面三自由度连杆机构的创新和应用提供了理论基础和依据。

By using graph theory, the number synthesis of planar 3- DOF eight--bar and ten--bar mechanism type is analyzed. Using the result of number synthesis and starting from the topology, the kinematic chain basic structure type of planar 3--DOF eight--bar and ten--bar mechanism is studied and analyzed. Starting the moving performance, five kinds of basic mechanism type of eight--bar and forty kinds of basic mechanism type of ten--bar mechanisms kinematic chains are obtained. A theoretical basis and foundation for the innovation and application of planar 3--DOF mechanism is provided.
