According to one embodiment of the present invention, a damper for reducing vibration of a main engine comprises: a housing of which one side is coupled to a hull of a ship, storing a magnetorheological fluid therein; a central shaft of which one end is coupled to a main engine and the other end is exposed to the outside of the housing to be provided as a free end, penetrating the housing to be coupled to the housing; and a piston provided inside the housing to be coupled to the central shaft. A coil is wound around the outer circumferential surface of the housing, and a particle chain can be formed between the housing and the piston when a current is applied to the coil. |
