This invention concerns a device for vibration damping of an object (1) moving along a trajectory arranged on a frame (7), whereas the object (1) involves spaces filled-in with magnetorheologic fluid which moves towards the object (1) and the device contents at least one control electromagnet (2,12) for achieving magnetorheologic fluid condition change to which a signal for vibration damping is fed from a control unit, whereas the control electromagnet/s (2,12) is/are arranged firmly on the frame on which the object's (1) trajectory is positioned. The control electromagnets (2,12) are arranged evenly with regard to the object's (1,5) trajectory (4,14), in case of need evenly to one another. In case of an object (1) pivoted on a frame (7) and fitted with at least one centrifugal pendulum (6) connected to the object (1) through a damper (11) with magnetorheologic fluid which moves towards the object (1) and the device involves at least one control electromagnet (12) for achieving magnetorheologic fluid condition change, to which a signal is fed from a control unit, at least one control electromagnet (12) regulated by controllable power supply for electromagnetic field intensity control is arranged along the circular trajectory (14) of the dampers (11) on the frame (7).
