本文设计了一种具有低频减振能力的轻质圆柱蜂窝夹层结构。基于Love壳理论建立了一个分析模型，研究了正交各向异性圆柱壳在局部共振器作用下的频散关系。低频带隙和负的有效质量密度的存在被确认解析。讨论了曲率和正交各向异性对波传播特性的影响，并给出了工程设计中的带隙预测公式。为了验证该设计方法的可行性，首先设计并制作了一个真实的圆柱形蜂窝超元结构。采用数值模拟和实验验证相结合的方法研究了所提出的圆柱形元结构的受迫振动响应。此外，还对内部带有板的圆柱形元结构进行了数值和实验研究，证实了其在实际应用中优良的振动抑制性能。本文的研究对于推动局部共振元结构在工程领域的应用具有重要意义。
In this study, a lightweight cylindrical honeycomb sandwich structure with low-frequency vibration attenuation ability is designed. An analytical model based on Love shell theory is established to investigate the dispersion relations of an orthotropic cylindrical shell with local resonators. The low-frequency band gaps and the presence of negative effective mass density are confirmed analytically. Subsequently, the influences of curvature and orthotropy on wave propagation behavior are discussed and the prediction formula for band gaps is defined for engineering design. To verify the feasibility of the design method, a real cylindrical honeycomb sandwichmeta-structure is first designed and fabricated by introducing local resonators into a square honeycomb structure. The forced vibration response of the proposed cylindricalmeta-structure is studied using both numerical simulations and experimental validation. Furthermore, a cylindricalmeta-structure with a plate inside is studied numerically and experimentally, which confirms its excellent vibration suppression performance in actual applications. This study is of great significance in promoting the application of local resonancemeta-structures in engineering field.
