“…In addition, some researchers focus on the sandwich metamaterial structure with integrated vibration resonator in the core to achieve vibration reduction and sound insulation. [32][33][34][35][36][37][38][39][40][41] The lightweight sandwich plate has excellent mechanical properties. By introducing the vibration resonator into the lightweight sandwich plate may promote the development of multifunctional metamaterials.…”

A metamaterial plate with multi bandgaps is proposed for vibration suppression by integrating membrane-mass structures that can be used as locally resonant metastructure into a honeycomb sandwich structure. The finite element method is employed to calculate the band structure and the transmission spectra. The formation mechanisms of the locally resonant bandgaps are investigated via the analysis of the mode shapes of the membrane-mass resonator and face plate in a unit cell. The effects of the location of the attached mass on the bandgap property and an improved multi bandgaps structure is designed and discussed. Results show that the proposed multifunctional metamaterial exhibits an excellent vibration suppression performance, as well as a significant designability. Moreover, a specimen of the proposed metamaterial is fabricated and experimental measurements are performed, and a good agreement between the numerical predictions and the experimental results is obtained. The results of this study will be useful for the design of sandwich structures with multiple vibration bandgaps.
