Extreme values revelation of magnetorheological transformers dynamic rigidity of hydromounts

This article presents the influence of phase mismatch on frequency shifts between incoming vibration signals and managing ones of magnetorheological transformer excitation (MRT) depending on hysteresis effects of ferromagnetic cores. Magnetorheological fluids (MRF) relaxation times as a result of disappearance of orthogonal magnetic fields are shown. The compensation of residual magnetic induction depending on ferromagnetic cores MRT hysteresis of the hydromount may be carry out by the shift of function intensity phase displacement as well as magnetic field intensity with the managed time lag of the first harmonic vibration signal.
