“…[3] Conducted system work for mechanic performance of very light sandwich plate with frictional pyramid core. Besides, sandwich structure could be applied to reduce structural vibration and noise level by selecting reasonable core material [4][5]. For a sandwich shell, the final design is to be made for good vibration and noise reduction.…”

To get clear the vibration mechanism of sandwith shell using the experiment method, a double-layered plate is designed for the sandwich shell by matching the equivalent impedance. Numerical analysis is conducted, and In 10Hz-4000Hz, the differenceof impedance from double-layered plate and sandwich shell should be less than 10%. A new design is given for the double-layered plate, and which is quite simple for construction. Then, the double-layered plate could be applied to conduct series vibration tests to get clear the influence of sandwich core material on structural vibration, while it could also reduce the costs of money and construction time.

“…Therefore, FADs can be designed to meet the vibration isolation frequency requirements in practical engineering to protect the building. In recent years, many scholars have studied the theory and application of periodic wave barriers, such as periodic piles (Cheng et al., 2013; Liu, Qin, & Yu, 2020; Meng & Shi, 2019), periodic walls (Huang et al., 2017; Marfia & Sacco, 2012), periodic lattice sandwich panels (Yu & Miao, 2019), which can all be used in the real‐life civil/infrastructure engineering to attenuate vibrations caused by cars, railways, subways, or earthquakes.…”

This study presents a new deep learning (DL) model to design topological configurations of periodic wave barriers to meet different target frequencies and site conditions. The new DL model is composed of an auto‐encoder (AE) and a conditional variational AE, and 230,000 sets of data are generated for training, validating, and testing it. The designed results are in good agreement with the targets, and it only takes a few seconds to complete a design. Two barriers are designed by the proposed method for two practical examples, and the vibrations in peak frequency ranges are attenuated. The DL model makes the design of periodic wave barriers smarter and more efficient.

“…They demonstrated that the sound insulation of sandwich structures improved significantly because of the stop band design of the sandwich plates. Recently, Yu and Miao (2019) numerically and experimentally studied the vibration isolation performance of a phononic crystal sandwich plate with periodic hollow tube core. Results showed that the proposed periodic sandwich structures could possess excellent attenuation performances of structural vibration because of the Bragg scatter band gap characteristics of periodic sandwich structures.…”

Sandwich structures are widely used in the fields of aerospace, automobile as well as ship and offshore structures because of their excellent mechanical performances such as lightweight, high specific strength and high specific stiffness. In this study, the flexural wave band gaps and vibration isolation characteristics of sandwich plate-type elastic metamaterials are numerically and experimentally investigated. The proposed sandwich plate-type elastic metamaterials are constituted of local resonant stubs periodically deposited on a sandwich plate with periodic thin-wall aluminium tube cores. An efficient finite element method combined with a solid-shell coupling method and Bloch periodic boundary conditions is presented and validated by experimental measurements to calculate the dispersion relations and the acceleration frequency responses of sandwich plate-type elastic metamaterials. The influences of geometric parameters on the flexural wave band gaps are performed and discussed. Results show that the proposed sandwich plate-type elastic metamaterials can yield flexural wave band gaps in the low-frequency range and show significant performance on the flexural vibration isolation. Moreover, the flexural wave band gaps can be effectively modulated by the geometric parameters.
