Solution and Simulation of Position-Orientation for Multi-Spatial 3-RPS Parallel Mechanisms in Series Connection

Notice of Retraction: Kinematics and dynamics simulation of the Slider-Crank mechanism based on Matlab/Simulink

“…Huang, Hadeby and Sohlenius [5] presented a connection method for dynamic modelling of a parallel kinematic machine by introducing active and passive matrices. A simulation mechanism of a spatial manipulator formed by 3-RPS parallel mechanisms is constituted and some computer simulation of this novel spatial manipulator are conducted and analyzed by Lu and Leinonen [6]. To quantitatively evaluate the dynamic changes to the texture of foods during chewing, a mchatronic device is required to reproduce human chewing behavior by Daumas, Xu and Bronlund [7].…”

Dynamics model of redundant hybrid manipulators connected in series by three or more different parallel manipulators with linear active legs

“…The 3-RPS type PM has a large orientation workspace and small position workspace [8]; the 3SPR + 3SPR type PM 1 + PM 2 has a large position workspace and less orientation workspace [9]. When the upper 3RPS type PM is connected in series with the lower 3SPR + 3SPR type PM 1 + PM 2 , their merits are made up mutually.…”

Analysis of stiffness and elastic deformation of a 2(SP+SPR+SPU) serial–parallel manipulator

“…Based on two kinds of 3UPU manipulators, Zheng et al [9] analyzed displacements of a hybrid S-PM. Lu and Leinonen [10] put forward a 2(3-RPS) S-PM and studied its displacement kinematics. They proposed a 2(3-SPR) S-PM and solved its active forces by CAD variation geometry [11] and also solved its velocity, acceleration, and statics by analytic approach and proved that the 2(3-SPR) S-PM has a much larger position and dexterous workspace than 2(3-RPS) S-PM [12].…”
