Description
Summary: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.
