Study on the Vibration Damping Performance of the Membrane-type Metamaterial

Based on the resonance consumption mechanism of thin-film metamaterial, thin-film metamaterial samples which can be used for vibration damping are designed and fabricated. The vibration test system is adopted to study the vibration damping performance of the membrane metamaterial.Resultsshow that the 1.3 mm thick thin-film metamaterial can attenuate vibration off the controlled object by 9 dB. Metamaterial samples designed with small thickness can effectively absorb vibration.
