In the present work preparation and dynamic characterization of polymer-based magnetorheological elastomer (MRE) is studied for vibration isolator. The magnetorheological elastomer is prepared with silicone rubber and carbonyl iron particles. Dynamic characterization of polymer-based MRE is done under different of Magnetic field, strain amplitude and frequency with rheometer. Experiment is carried out to find the shift frequency of MRE vibration isolator. Results shows the shear modules and loss factor of MRE changes with change in frequency, strain amplitude and magnetic field. the shift frequency of the 6 Hz from 30 Hz to 36 Hz that more effective in reducing the amplitude of vibration compared to passive isolator.
