Testing of magnetorheological fluids for shock loadings

Abstract

The problem of applying magnetorheological fluids in damping systems of shock loadings is considered. The physical prerequisites of controlling the characteristics of magnetorheological fluids with internal electromagnetic fields are examined. Processes occurring in magnetorheological fluids under shock loadings are studied. The criterion for selecting a magnetorheological fluid for such problems is the appearance of electromagnetic pulses on windings of solenoid designed to generate an internal controlling magnetic field. The amplitude and duration of these pulses is a function of shock loadings. It is necessary to take their influence into account when developing magnetorheological dampers for shock loadings.
