摘要

在轻量化工程结构中实现优异的振动抑制一直是人们关注的长期挑战。为此,本研究将声黑洞(ABH)概念融入到点阵结构中,构建了声黑洞点阵结构(ABH- lattice)。在这项工作中,提出了一种新的abh晶格设计,用晶格单元尺度上有效力学性能的梯度参数化取代传统的厚度变细。采用非均匀欧拉-伯努利梁模型结合动力均匀化技术建立了设计方法。数值和实验研究证实了abh晶格在频域和时域上的抑制振动性能。采用基于微扰的分析来揭示abh晶格特殊减振能力背后的潜在能量收敛现象。进一步推导了控制能量收敛效应的有效参数,并用于研究结构参数对振动抑制的影响。最后,研究了局部谐振腔与abh晶格的集成,揭示了显著的协同效应。这种耦合显著地扩大了局部共振带隙。这种创新的网格结构ABH设计满足了工程对减振的要求,为实际应用中的振动控制提供了简单而有效的解决方案,并在工程实施中具有巨大的潜力。

Inhomogeneous acoustic black hole lattice design for superior vibration suppression

Inhomogeneous acoustic black hole lattice design for superior vibration suppression
Achieving superior vibration suppression in lightweight engineering structures has been a long-standing challenge of considerable interest. In response, this work integrates the acoustic black hole (ABH) concept into lattice structures, constructing the acoustic black hole lattice structures (ABH-Lattice). In this work, a novel design for ABH-Lattice is proposed, replacing conventional thickness tapering with gradient parameterization of effective mechanical properties at lattice units scale. The design methodology is established using the inhomogeneous Euler-Bernoulli beam model combined with the dynamical homogenization technique. Numerical and experimental investigations confirm the vibration suppression performance of ABH-Lattice, in both frequency and time domains. A perturbation-based analysis was employed to reveal the underlying energy convergence phenomenon behind the exceptional vibration damping capabilities of the ABH-Lattice. Furthermore, the effective parameter governing the energy convergence effect is derived and used to study the influence of structural parameters on vibration suppression. Finally, the integration of local resonators with the ABH-Lattice was investigated, revealing a remarkable synergistic effect. This coupling significantly expanded the local resonance bandgap. This innovative ABH design for lattice structures meets engineering demands for vibration reduction, providing a simple yet effective solution for vibration control in practical applications and holding significant potential for engineering implements.

期刊介绍: The International Journal of Mechanical Sciences (IJMS) serves as a global platform for the publication and dissemination of original research that contributes to a deeper scientific understanding of the fundamental disciplines within mechanical, civil, and material engineering. The primary focus of IJMS is to showcase innovative and ground-breaking work that utilizes analytical and computational modeling techniques, such as Finite Element Method (FEM), Boundary Element Method (BEM), and mesh-free methods, among others. These modeling methods are applied to diverse fields including rigid-body mechanics (e.g., dynamics, vibration, stability), structural mechanics, metal forming, advanced materials (e.g., metals, composites, cellular, smart) behavior and applications, impact mechanics, strain localization, and other nonlinear effects (e.g., large deflections, plasticity, fracture). Additionally, IJMS covers the realms of fluid mechanics (both external and internal flows), tribology, thermodynamics, and materials processing. These subjects collectively form the core of the journal's content. In summary, IJMS provides a prestigious platform for researchers to present their original contributions, shedding light on analytical and computational modeling methods in various areas of mechanical engineering, as well as exploring the behavior and application of advanced materials, fluid mechanics, thermodynamics, and materials processing.
