Abstract
The issues of dynamic stiffness coefficient control and increasing the damping ability of magnetorheological vibration mounts (MR-hydromounts) are considered. It is shown that in order to reduce the dynamic stiffness coefficient and increase the damping ability of the MR-hydromount it is necessary to reduce the coefficient of hydraulic resistance of the working magnetorheological fluid flow, which can only be achieved by increasing the number of throttle channels in the baffle plate. Calculation of the dynamic stiffness coefficient of the MR-hydromount depending on the magnetic field strength in the magnetorheological fluid and its heating temperature is presented. Keywords: inertial transformer, magnetorheological transformer, magnetorheological fluid, hydromount, working fluid, heating temperature, dynamic stiffness coefficient. gord349@mail.ru, acidwolfvx@rambler.ru, oxulkovs@mail.ru, aplehov@mail.ru, dm_titov@list.ru
