Motion platform selects a connection level to web member or Vertical dimension web member; Level to gear train and Vertical dimension gear train separate.Level to be moved and the motion of Vertical dimension can not interfere to gear train and the separate horizontal direction that refers to of Vertical dimension gear train.
Further, moving component and a fixed mount of Vertical dimension shaking table are fixed, and fixed mount is provided with the locating slot of the upper level in location to reed, and the corresponding level of each locating slot is to reed; Lower level is relative with the moving component of Vertical dimension shaking table fixing to reed.Fixed mount can be fixedly installed on the moving component of Vertical dimension shaking table with securing member, also can be one-body molded with the moving component of Vertical dimension shaking table.Lower level both can be directly fixed on the moving component of Vertical dimension shaking table to reed, also can be fixed on fixed mount.
