Abstract

New experimental results on the capability of innovative elasto-magnetic composites to produce high attenuation of the relative oscillation between two bodies with different rigidities, as well as to elude the resonance effects, are reported. A simple, but very efficient, model of the innovative attenuator working principle, including the determinant role of magnetic force change with vibration, is proposed and its agreement with experimental features is explained. Peculiar potentialities for optimal application of the innovative composite elasto-magnetic attenuators are outlined.

Keywords
