Based on the theory of screws and the principle of one leg driving by a independent motor, a method of structural synthesis of Fully-decoupled three-translational and two-rotational (3T2R) parallel mechanisms was proposed, the parallel mechanism adopted with Independent drive whose output link is provided by the corresponding motion. Firstly, according to the prescribed characteristics of each mechanism...
This paper proposed a structural synthesis method of LEMs both with prismatic joint and revolute joint, which can solve the problem of frame and driver link transformation. First, equate the LEMs in the plane with the planar kinematic chains, and then construct the group-based adjacent matrix of the planar kinematic chains, and to solve all possible connection mode of planar mechanism which is given...
This paper presents a novel method of structural synthesis and analysis of hybrid mechanisms based on the set theory. The basic concept of GF set, algorithms and the type synthesis principle based on GF set are firstly introduced. The topological arrangements of hybrid mechanisms can be developed by the elements of GF set combination and rotation axis transfer theorem to obtain the multi-loop forms...
