Magnetorheological elastomer (MRE) is a new class of smart materials, whose mechanical properties can be continuously and rapidly controlled by an applied magnetic field. A compression MRE isolator was designed and fabricated. The mechanical tests were conducted by instron. The dynamic properties of MRE isolator were studied by frequency sweeping tests, using vibration table under 1 g acceleration excitation with different currents. The peak value of the transmissibility was decreased by 29.7% and the natural frequency of the single degree of freedom (SDOF) system approximately increased by 18.54% while the current varied from 0.0 A to 4.0 A. Moreover, the equivalent stiffness and damping coefficients were identified from experimental data. In order to further evaluate the effectiveness of MRE isolator for vibration control, the SDOF inertial measurement unit (IMU) isolation system was simulated under random vibration conditions. The peak acceleration of power spectral density (PSD) was decreased by 48.8% when applying a series of constant currents. The study verifies that the compression MRE isolator is capable of increasing system stiffness, changing system natural frequency and decreasing system vibration.
