Abstract
The research presented in the work focuses on a damper that utilizes an "intelligent" material called multilayer magnetorheological elastomer. These devices are of interest due to their ability to adjust the elastic properties, size, and shape of the working body by manipulating the external magnetic field. They also have a high load capacity. The effectiveness of the damper's vibration isolation is determined by its design, manufacturing technology, and the composition of the multilayer magnetorheological elastomer. The mechanical and magnetic hysteresis of the device allows for evaluating the controllability of the damper and its ability to absorb vibrations. Research results indicate the presence of a symmetric and narrow hysteresis loop, not exceeding 7 μm, within the operating range of control currents.
