Abstract：Magnetorheological elastomer is a kind of smart material whose shear modulus can be controlled by external magnetic field, and it has broad application prospects in semi-active controlling, landing buffering and so on. In this paper， the isolator’s magnetic circuit design are studied and one isolator based on MR elastomer is designed, whose response performance of vibration control is studied by changing controllable current and frequency of sine wave. The experiments implicates that it has good isolation performances within a certain frequency.
