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.

    본 발명의 일 실시예에 따른 주기관 진동 감쇠용 댐퍼는 내부에 자기유변 유체가 수용되며 일측이 선박의 선체에 결합되는 하우징; 상기 하우징을 관통하여 결합되며 일단은 주기관측과 결합되고, 타단은 상기 하우징의 외부로 노출되어 자유단으로 구비되는 중심축; 및 상기 하우징의 내측에 구비되어 상기 중심축과 결합하는 피스톤;을 포함하고, 상기 하우징의 외주면에는 코일이 권선되고, 상기 코일에 전류 인가 시 상기 하우징과 상기 피스톤 사이에 파티클 체인이 형성될 수 있다.
