Analysis and Simulation of a Parallel Platform with 2R-1T
Abstract:
It is described that a parallel platform with three spatial degrees of freedom; the platform is built up by parallel combination of three symmetrical (SPS) and a branched-chain (PU). It is gotten the freedom of the mechanism and the theory expression of inverse kinematics by theoretical calculation. The mechanism was modeled by Pro/E, and the model is imported with Mech/Pro to ADAMS/View for simulation. The trajectory of three kinematic chains that changes over time through computer simulation, which are got by exerting force on the moving platform, is compared with the theoretical calculation results gotten through MATLAB. The results prove that the curve of position is identical, and it testifies the correctness of the movement of the platform.
