Resum

We propose a composite structure with periodic additive acoustic black holes (ABH) to absorb vibrations from plates. Different from conventional embedded ABHs, this additive configuration no longer compromises structural integrity. A theoretical model is constructed to characterize the vibration of the coupled structure using Gaussian expansion method (GEM) and nullspace method (NSM). A finite plate with 4 × 4 cells has been examined. Results show that the additive ABHs can significantly mitigate the vibration of the host plate, even at low frequencies.
