Experimental Research of the Damping Properties of Magnetosensitive Elastomers

Popis výsledku v původním jazyce

The dependence of dynamical moduli and loss factor of magnetorheological elastomers (MREs) on the external magnetic field intensity and on the frequency of applied cyclic shear deformation was studied. Isotropic samples of MRE were made of the silicon rubber matrix filled by iron or carbonyl iron micro-particles. The magnetic field produced by an electromagnet was applied in course of cyclic loading of double-shear samples of MRE under controlled shear strain. Dynamical moduli and the loss angle were determined as the function of the magnetic field intensity and of the frequency of cyclic deformation in shear. The dynamic stiffness of MRE depends on magnetic flux density and increases with increasing testing frequency. The loss factor of MRE samples is tunable with the magnetic flux density and depends also on the testing frequency.
