title = "Broadband resonance suppressions using a resonant beam damper with embedded acoustic black hole features",
abstract = "This article presents a study of a novel vibration control device in the form of a resonant beam damper (RBD) with 'Acoustic Black Hole' (ABH) features. Both enriched dynamic characters of the ABH taper and enhanced system damping brought by ABH effects are exploited to develop this so-called ABH-featured RBD (ABH-RBD) for broadband vibration control. The numerical simulations and experimental measurements show that, without the tedious tuning process, the multiple resonant peaks of a primary structure can be suppressed effectively by the proposed ABH-RBD, except for some specific resonances. Three typical vibration control effects are found by a strategic parameter study: interaction dominated, damping enhancement and their combinations. Further analyses of these control mechanisms are carried out by contrastive studies with a uniform beam absorber. The influence of the attachment locations on the performance of ABH-RBD is also noticed and discussed.",
