Abstract

It is proposed to use magnetorheological suspensions in shock load damping systems. Physical substantiations and technological methods for obtaining magnetorheological fluids and the possibility of controlling their performance are considered. When obtaining a ferromagnetic powder, it is proposed to use a vortex cavitator, which provides constant sizes and shape of grains, high productivity, and excludes inclusions. The sensitivity of the powder to the influence of a magnetic field makes it possible to improve the well-known acoustic-cavitation process by supplementing it with an electromagnetic system that creates a vortex magnetic field of the required frequency. Keywords: magnetorheological suspension, ferromagnetic powder, magnetic particles, dispersion, acoustic cavitation, vortex cavitator, electromagnetic field, Maxwell's equations. gord349@mail.ru, oxulkovs@mail.ru, acidwolfvx@rambler.ru, ivanov.e.g@mail.ru, aplehov@mail.ru
