Abstract
Disclosed is an active control Stewart vibration damping platform, including a load-bearing platform, a base, and six telescopic rods. Each telescopic rod includes a driving motor, a rotating shaft, a sleeve, and a moving rod. One end, away from the driving motor, of the rotating shaft is provided with a cylindrical cavity, one end of the moving rod penetrates through the cylindrical cavity, and the sleeve is sleeved outside the rotating shaft. The rotating shaft is in running fit with the sleeve through a first bearing, and the moving rod is in sliding fit with the sleeve through a second bearing. The moving rod and the rotating shaft are respectively provided with a spiral permanent magnet. The spiral permanent magnet on the rotating shaft can drive the moving rod to move in an axial direction of the rotating shaft through the spiral permanent magnet on the moving rod when rotating.
