Oscillograms of changes in the accelerations of amplitudes, phases and oscillation frequencies under the action of specified loads at the input and output of the test sample of magnetorheological elastomer are recorded and analyzed. At the input, the sample is loaded with a smoothly increasing harmonic force arising from the imbalance of the unbalanced rotor of the electric motor. At the output, the sample is loaded with a magnetic field created by a neodymium magnet. A comparative analysis of the accelerations and oscillation phases of the test sample is given. An actively controlled damper based on a magnetorheological elastomer has been developed.
