Abstract: The definition of general reducible system is proposed. The relationship between the inputs and outputs of the 3-DOF translational parallel manipulator with independent motions is investigated. The definition of the 3-DOF reducible translational parallel mechanism is presented. Further more, the satisfying and necessary conditions for the judgment of this kind of mechanisms is given. A new Gf coordinates is defined for the type synthesis of the reducible parallel mechanisms. And five such mechanisms are presented. Taking one of them as example, a new optimization design method based on the workspace of the moving platform is also presented.
