... Abstract This paper presents a general graph grammar for structure synthesis of mechanisms. Much of current mechanism design is based on a systematic method popularized by Freudenstein, Buchsbaum, Mruthyunjaya and Tsai (among others). Since it relies on algebraic abstractions of graph theoretic...

... Abstract Based on the units of single-opened-chain limb, some topological characteristics of rank-degenerate parallel robot mechanisms are revealed, and a systematic and effective new method for structure synthesis of 4-DOF (3-translation and 1-rotation) parallel robot mechanism is put forward...

... 30 07 2010 Based on the Position and orientation characteristic (POC) equation of serial mechanisms proposed by the author, this paper presents a novel systematic approach for structure synthesis of rank-degenerated serial mechanisms and over-constrained single-loop kinematic chains...

... 30 07 2010 Basic principles and main characteristics of three approaches for structure synthesis of robot mechanisms (the screw theory-based approach, the displacement subgroup-based approach and the approach based on position and orientation characteristic (in short, POC...

... 30 07 2010 Based on previous research results presented by authors, this paper proposes a novel systematic approach for structure synthesis of all parallel mechanisms (excluding Bennett mechanism etc), which is totally different from the approaches based on screw theory and based...

... 18 06 2008 Based on topological structure characteristics of the parallel mechanisms, the internal relationship between kinematics decoupling and mobility types of mechanisms is revealed, and the basic principle for structural synthesis of topological decoupling mechanisms is put...

... 18 06 2008 Based on the units of single-opened-chains, some topological characteristics of rank-degenerated parallel manipulators are revealed, and a systematic and effective new method for structure synthesis of parallel manipulators with 3-dimension translation and 1-dimension...

... typified by robots es pecially multi-loop parallel robots, structure synthesis has be come a challengeable problem. Early research on robot mecha nisms focused on serial robots. In recent twenty years, paralle mechanisms have caught people s great attention. When paralle mechanisms are used for machine...
