Abstract

A new design of a passive damping support has been proposed. The working body of the support is made of a silicone composite material uniformly filled ferromagnetic powder. The working body of the damper was in a gradient magnetic field. The principle of operation of the damper is based on preliminary mechanical stress arising in the polymer matrix under the action of ponderomotive magnetic forces. A prototype device was manufactured and tested. The purpose of the tests was to test the operability of the new damper and study the effect of the gradient magnetic field on its vibration-isolating properties. The tests were carried out under the influence of vertical and axial vibration. The product protected from vibration (electronic components) was imitated using a load. The amplitude-frequency characteristics of the damper were built as a result of tests. Control tests were carried out in a zero magnetic field. The results of the control tests are presented in this article. A significant improvement in the damping properties of the device under the influence of a magnetic field during vibration at a resonant frequency is shown. Prospects for the use of magnetic silicone composites in vibration protection systems are described in this article.
