A Magnetorheological Transformer Controlled by a Rotating Magnetic Field

Abstract

New approaches to optimization of the parameters of a magnetorheological transformer are considered. The influence of the vortex magnetic field on the sedimentation of magnetic particles in a magnetorheological fluid changing its viscosity under the influence of an alternating magnetic field is considered. It is shown that it is advisable besides one throttle channel to enter an additional channel between coaxial cylinders, controlled by the rotating vortex magnetic field. The analysis of the constructed mathematical model revealed that with increasing the frequency of the fundamental harmonic of the input vibration signal, there is a frequency modulation of the controlling magnetic field.
