The present invention relates to a damper for decreasing vibration of a main engine, comprising: a cylinder, in which a magnetorheological fluid is accommodated, one side of which is coupled to a hull of the ship; a center shaft coupled through the cylinder and having one end coupled to a main engine and another end exposed to the outside of the cylinder and provided as a free end; and a piston provided at an inner side of the cylinder and coupled to the center shaft, provided with a coil winding portion that has a coil wound around an outer circumference thereof, and having a particle chain supporting vibration occurring in the main engine, wherein the particle chain is formed in a section formed in a magnetic field when a current is applied to the coil. In addition, a disc member disposed in at least one of an upper portion and a lower portion of the inner space of the cylinder is further included in the damper for decreasing vibration of the main engine.

    내부에 자기유변유체가 수용되며 일측이 선박의 선체에 결합되는 실린더와, 상기 실린더를 관통하여 결합되며 일단은 주기관측과 결합되고, 타단은 상기 실린더의 외부로 노출되어 자유단으로 구비되는 중심축 및 상기 실린더의 내측에 구비되어 상기 중심축과 결합되며, 외주면에 코일이 권선되는 코일 권선부를 구비하고, 상기 코일에 전류 인가 시 자기장에 형성되는 구간에 파티클 체인이 형성되어 상기 주기관측에서 발생되는 진동을 상기 파티클 체인이 지지하는 피스톤을 포함하며, 상기 실린더의 내부공간 상부와 하부 중 적어도 하나에 배치되는 디스크 부재를 더 포함하는 주기관 진동 감쇠용 댐퍼가 개시된다.
