Magnetorheological elastomer (MRE) is a new-type smart vibration isolation material, which is widely used in recent years. It not only has the traditional advantages of MRF such as controllable, reversible and fast response characteristics, but also has the characteristics of good stability, wear-resisting and anti-settling. It is widely used in high-tech vibration isolation fields. In this article, a new-type MRE with rubber as matrix was developed. According to MRE controllable stiffness and damping characteristic, a new MRE vibration isolator was designed and the vibration response characteristics under different external controlled current and excitation frequency were tested experimentally. The test results show that when the external current changes, the vibration isolator stiffness also changes, so that the natural frequency also changes and the effect of the broadband vibration isolation is achieved.
