Vibration reduction using membrane-mass resonators

摘要

This study presents a metamaterial beam consisting of periodic holes with membrane-split-ring resonators. Finite element (FE) models are constructed and used to predict the dispersion relation of the metamaterial beam. Numerical results show that both Bragg-type and resonant- type bandgaps exist in such a structure. Bragg-type bandgaps are usually occurred at high frequencies; resonant-type bandgaps can be tuned by altering the properties of local resonator. Experimental measurements are conducted to validate the FE results. It is found that when the excitation frequency is close to the local resonance, elastic wave is attenuated and the beam remains motionless.
