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.
