A kinetostatic model and a dynamics model of a parallel manipulator (PM) with three grippers are established and analyzed in the light of its application. First; the coordinative kinematics of this manipulator and three grippers are analyzed. Second; the kinetostatic formulae are derived for transforming the coordinative kinematics and forces applied on the grippers into the workloads applied on the moving platform and the active/constrained forces and torques applied onto active legs. Third; the dynamics formulae are derived for solving dynamic active wrench of grippers and PM by considering inertial mass of the grippers; legs and platform. Finally; a numerical example is given for illustrating application of kinetostatic model and dynamics formulae; and the dynamics solutions of this manipulator are verified by simulation;
