Based on spatial flexible joint translational parallel vibration exciting means

The present invention discloses a translational parallel excitation device based on spatial flexible joint, the device is a one-dimensional moving platform shaker, static platform, the same configuration of the flexible branch and the three parameters of the three identical composition, characterized in wherein: each of the flexible branches corresponding to respective one-dimensional movement of the exciter consisting of a branched RPRP type, motion type RPRP the top branched connector fixed to the movable platform, said support by a screw-type exercise RPRP the bottom end of the connector is fixed to the stationary platform, said three branched RPRP type motion around said central axis of static platform uniformly distributed by a screw. Thereby achieving spatial position change of the three translational, three translational simulate real-world conditions dither space.
