A damper for decreasing the vibration of a main engine according to an embodiment of the present invention, which is to decrease vibration transferred from a main engine, comprises: a housing which receives magnetorheological fluid therein and has one side coupled to the hull of a ship; a center shaft which is coupled by penetrating the housing and has one end coupled to a main engine and the other end exposed to the outside of the housing to be used as a free end; and a coil winding part which is formed on the inner side of the housing to be coupled to the center shaft and allows a coil to be wound on the outer surface thereof. A particle chain of a piston is formed in a section where a magnetic field is formed when electric currents are applied to the coil and supports vibration occurring in the main engine.

    본 발명의 실시예에 따른 주기관 진동 감쇠용 댐퍼는 주기관에서 전달되는 진동을 감쇠시키기 위한 것으로 내부에 자기유변유체가 수용되며 일측이 선박의 선체에 결합되는 하우징; 상기 하우징을 관통하여 결합되며 일단은 주기관측과 결합되고, 타단은 하우징의 외부로 노출되어 자유단으로 구비되는 중심축; 및 상기 하우징의 내측에 구비되어 상기 중심축과 결합되며, 외주면에 코일이 권선되는 코일 권선부를 구비하고, 상기 코일에 전류 인가 시 자기장이 형성되는 구간에 파티클 체인이 형성되어 상기 주기관측에서 발생되는 진동을 상기 파티클 체인이 지지하는 피스톤;을 포함할 수 있다.
