Disclosed is a variable bushing system using a magnetorheological elastomer (MRE). The variable bushing system using a magnetorheological elastomer comprises: a bushing formed by an MRE hardened or softened depending on whether a magnetic field is applied; a measurement device measuring a size of vibration of a vibration controllable object; an electromagnet applying the magnetic field to the MRE; and a controller controlling the electromagnet according to the measured size of the vibration to control hardness of the bushing. 자기유변탄성체를 이용한 가변형 부싱 시스템이 개시된다. 자기유변탄성체를 이용한 가변형 부싱 시스템은, 자기장의 인가 여부에 따라 굳어지거나 물러지는 자기유변탄성체(MRE: Magneto Rheological Elastomer)로 형성된 부싱, 진동제어 대상체의 진동 크기를 계측하는 계측기, 자기유변탄성체로 자기장을 인가하는 전자석 및 계측되는 진동 크기에 따라 전자석을 제어하여 부싱의 경도를 조절하는 제어기를 포함한다.
