PurposeIn order to investigate the vibration reduction properties of a three-dimensional elastic metastructure with spherical cavities at low frequencies.Design/methodology/approachThe bandgap characteristics of a three-dimensional elastic metastructure with spherical cavities are studied based on analytical and numerical approaches.FindingsThe results of both method revealed that the vibration of the vertexes masses is important for opening bandgaps. The fact that the big sphere cavity radius or short side length of the cube unit leads to a wider bandgap, is noteworthy.Originality/valueThis research provides theoretical guidance for realizing the vibration attenuation application of EMs in practical engineering.

“…Therefore, vibration suppression plays a critical role in engineering applications. Acoustic metamaterials (AM) are artificial materials with supernatural physical properties, such as negative effective mass [4] and negative effective modulus [5]. Due to the existence of band gaps in the AM, it can cause the significant attenuation of elastic waves, which has great potential values in the field of vibration reduction [6].…”

In this paper, a novel acoustic metamaterial beam attached with lattice structures and resonators is designed for elastic wave attenuation. The proposed acoustic metamaterial beam is fabricated by 3D printing with NiTi alloy. Theoretical analysis using negative effective mass is performed to derive the band gap of structure. The finite element method and experimental analysis are performed to investigate the dispersion relation and transmission spectrum. Furthermore, the effect of geometric features on the band gap is studied by simulations. Results proved that the metamaterial beam can be utilized for the control of low-frequency vibration.

Broadband Vibration Attenuation Achieved by 2D Elasto-Acoustic Metamaterial Plates with Rainbow Stepped Resonators

This paper investigates the influences of nonperiodic rainbow resonators on the vibration attenuation of two-dimensional metamaterial plates. Rainbow metamaterial plates composed of thin host plates and nonperiodic stepped resonators are considered and compared with periodic metamaterial plates. The metamaterial plates are modelled with the finite element modelling method and verified by the plane wave expansion method. It was found that the rainbow metamaterial plates with spatially varying resonators possess broader vibration attenuation bands than the periodic metamaterial plate with the same host plates and total mass. The extension of attenuation bands was found not to be attributed to the extended bandgaps for the two-dimensional metamaterial plates, as is generally believed for a one-dimensional metamaterial beam. The complete local resonance bandgap of the metamaterial plates is separated to discrete bandgaps by the modes of nonperiodic resonators. Although the additional modes stop the formation of integrated bandgaps, the vibration of the plate is much smaller than that of resonators at these modal frequencies, the rainbow metamaterial plates could have a distinct vibration attenuation at these modal frequencies and achieve broader integrated attenuation bands as a result. The present paper could offer a new idea for the development of plate structures with broadband vibration attenuation by introducing non-periodicity.
