“…Dai et al provided a review of the use of acoustic materials in vibration and noise control. Acoustic metamaterials are classified into passive acoustic metamaterials and active acoustic metamaterials based on their response mode [104]. Further, acoustic metamaterials can be subdivided into sound-insulating metamaterials and sound-absorbing metamaterials.…”

As rail transportation continues to advance, it provides significant convenience to the public. However, the environmental vibration and noise generated during its operation have become major concerns for residents living near rail lines. In response to these concerns, the “Law on the Prevention and Control of Noise Pollution” was promulgated in China, bringing attention to this issue within the rail transportation sector. This review summarizes the regular features observed in environmental vibration and secondary structural noise tests on different sections, including embankment sections, bridge sections, underground railroads and vehicle sections. Furthermore, it introduces several physical models utilized in the study of environmental vibration and secondary structural noise, focusing on three key aspects: excitation sources, propagation paths and the modelling of building structures. This paper also explores the introduction of data-driven models related to big data and artificial intelligence to enhance the accuracy and efficiency of research in this field and provides an overview of commonly used measures to control train-induced environmental vibrations and secondary noise in buildings. These measures are discussed in terms of excitation sources, propagation paths, and receivers, offering insights into effective strategies for mitigating the impact of rail transportation on nearby residents. Finally, this study highlights the primary findings and offers pertinent recommendations. These recommendations include considerations regarding both laboratory and on-site testing procedures, challenges associated with the deployment of data-driven models and key parameters for designing and utilizing low-stiffness fasteners.

“…In the realm of metamaterials, this technique empowers designers to exert precise control over microstructures and achieve tailored performance optimization [24][25][26]. Through the utilization of multi-material and multi-level stacking techniques, additive manufacturing not only enhances the strength [27,28], toughness [29,30], and deformation [31,32] of metamaterials but also facilitates continuous exploration into novel metamaterials for vibration and noise reduction [33,34]. Shojaee et al [35] introduced a multi-scale modeling framework for shell lattice metamaterials.…”

Strength and band gap are the two basic physical features of the cubic metamaterial. How to design band gap characteristics with high strength of structure is the key for the further industrial application in vibration control of the cubic metamaterial. Here a cubic metamaterial is designed by optimal selection of crystal orientation angle to obtain wide band gaps with high strength. The prototype samples were fabricated using advanced additive manufacturing technology to tensile-pressure experiments and sine frequency sweep experiment, thereby demonstrating the validity of the obtained results. Results indicated that the normalized bandwidth of SC metamaterials is 0.47 and the ultimate strength is 25.99 MPa. The normalized bandwidth is increased by 3.1 times and 47 times higher than that of the metamaterials of FCC and BCC. Its ultimate strength is increased by 3.5 times and 6.7 times. The static simulation results revealed that the maximum mises stress values of SC, FCC, and BCC metamaterials were 1.71MPa, 10.49MPa, and 31.40MPa respectively. The attenuation amplitude of the elastic wave measured by experiment is 80dB, which is consistent with the simulation results. The bandwidths of cubic metamaterials exhibit a positive correlation with their strength. The variation in crystal orientation angles plays a crucial role in elucidating the underlying mechanism behind the positive correlation between the strength and the band gap. The further buckling analysis of SC metamaterial with high strength and wide bandgap characteristics reveals that the negative Poisson's ratio structure experiences a reduction in bandwidth and strength as buckling deformation intensifies.
