Nowadays, acoustic black holes (ABHs) are very popular for producing efficient vibration reduction at high frequencies in combination with some damping mechanisms. However, its low-frequency performance is hard to improve since the ABH effect principally occurs beyond cut-on frequency. Fortunately, periodic configuration offers bandgaps below that frequency wave attenuation. In this chapter, a topological structure suggested produce new bandgap low frequencies, by taking supercell and decreasing distance. The Rayleigh-Ritz method (WRRM) adopted compute complex dispersion curves. Examinations of curves transmissibilities confirm efficiency capability proposed ABHs.

Vibrations generated from machinery in various industries, such as the automotive, aerospace, and shipbuilding must be suppressed for developing low-vibration low-noise systems. High-frequency vibrations can easily controlled via damping treatments; however, controlling low-frequency range large is a major challenge. In general, substantial amount of material required suppressing vibrations. This unsuitable when low-cost, lightweight, eco-friendly To overcome limitations, effective methods are these this study, an method was proposed using multiple acoustic black holes (multi-ABHs) considering suitability values attachment positions, which were determined by flexural wave propagation interactions between multi-ABHs structures. The positions non-dimensional parameters that calculated structural intensity mode superposition methods. For validating method, vibration suppression characteristics analyzed steel plate. cases categorized into six groups according to multi-ABHs. largest reduction observed attached location with highest cases. Finally, applied 2-pole motor dominant at 60, 120, 180 Hz frequencies suppressed.
