Influence of Magnetic-Viscous Friction on the Properties of a Magnetorheological Hydraulic Mount

The article provides theoretical substantiation for the necessity of analyzing the joint operation of the mechanical and hydraulic subsystems of a magnetorheological hydraulic anti-vibration mount (MR hydromount). Experimental studies are conducted on MR hydromounts OGM-95 with a low eigenfrequency. It is confirmed that the mechanical and hydraulic subsystems of MR hydromounts require configuration in order to achieve the greatest vibration damping in the pre-resonance frequency region. The mounts are controlled by synchronous configuration of the phase and frequency of the control signal of the magnetorheological transformer with the fundamental oscillations harmonic reaching the frequency of mechanical resonance of the MR hydromount.
