Claims

[Scope of utility model registration request]

Controls the operation of a vibration damper that generates a variable excitation force in the opposite phase to these vibrations in order to eliminate ship vibrations caused by the main engine and propeller fluctuations in water pressure. The controller includes a rotation signal detector that detects the rotation speed of the propeller shaft, a hull load information input means that inputs hull load information, and a memory that stores control information, and the controller Control information on the rotational speed, excitation force, and phase of the vibration damper is obtained from control information preset in the storage device according to the rotation signal from the detector and the hull load information from the hull load information input means. A ship body vibration damping device, characterized in that it is configured as a controller that controls the vibration damper to output an excitation force equal to and in opposite phase to the ship body vibration through the controller.
