Automation of a test bench for studying the magnetic hysteresis of a damper based on multilayer magnetorheological elastomer

The widespread use of electronic precision equipment necessitates research aimed at the development and improvement of vibration protection means. This study presents an investigation of a damper, the operating principle of which is based on the use of an "intelligent" material – a multilayer magnetorheological elastomer. The interest in such devices is due to their ability to adjust the elastic properties, sizes, and shapes of the working body by changing the external magnetic field, as well as the high load-bearing capacity of such devices. The effectiveness of active vibration isolation using the damper is determined by the quality of its transient processes, manufacturing technology, and the composition of the multilayer magnetorheological elastomer. The transient process time allows for determining the system's responsiveness, and consequently, the frequencies within which the device can operate effectively in active mode. The research results showed that the maximum transient process time was 106 ms, which corresponds to effective operation in the low-frequency range up to 9,5 Hz.
