Type Synthesis of Fully-decoupled Three-rotational and Three-translational Parallel Mechanism by Zhou Hui, Cao Yi

“…Firstly,based on the requirement of the Jacobian matrix of full-coupled parallel mechanism is the nonzero diagonal matrix,by using the screw theory,both the positive and the inverse Jacobian matrix meeting the expected requirement are constructed. The actuation screws of branch chain drive pair acting on the moving platform is determined,and the motion screw system of corresponding branched chain is obtained,and the branch chain structure screw system configuration can be completed by this. …”
