Abstract: A hierarchical approach for the lightweight design of a 3-SPR parallel mechanism (PM) is presented in this paper. The criterion to match the rigidities of the limb body and those of the joints is proposed; meanwhile, the ...

Abstract: A threerevolute prismatic spherical (3RPS) parallel kinematic machine (PKM) module is proposed as an alternative solution for highspeed machining (HSM) tool. Considering the PKM as a typical compliant parallel device, whose ...

Abstract: Wind is the main factor that affects soil erosion and the severity of wind-sand disasters. Therefore, it is of critical importance to analyze the influence of remodeling topography units on the near-surface wind conditions ...

Abstract: Taking the well-known Tricept robot as an example, this paper presents a semi-analytical approach for elastodynamic modeling of five or six degrees of freedom (DOF) hybrid robots composed of a 3-DOF parallel mechanism plus ...

Abstract: Drawing mainly on the concepts of dual space and dual basis in linear algebra and on existing screw theory, this paper presents a novel and systematic approach for the force/motion transmissibility analysis of 6DOF parallel ...

Abstract: By drawing on the duality of twist space and wrench space, this paper presents a general and systematic approach for force/motion transmissibility analysis of lower mobility nonredundant and nonoverconstrained parallel ...

Abstract: Mainly drawing on screw theory and linear algebra, this paper presents an approach to determining the bases of three unknown twist and wrench subspaces of lower mobility serial kinematic chains, an essential step for ...
