Study of magnetically active elastomers resonance and damping properties

Abstract

The dynamic properties of magnetically active elastomers based on silicone polymer matrix with various ferromagnetic fillers under the external magnetic fields influence using a vibration-testing complex have been studied. The amplitude-frequency characteristics and the investigated composites resonance frequencies changes under such influences are established. Calculated dependences for determination tested samples damping properties are given. Analysis of the obtained data revealed a damping coefficients decrease in the investigated materials with an magnetic forces increase acting on the investigated magnetoactive elastomers.
