Cut-out resonators for tuned vibration suppression of plates
https://orcid.org/0000-0003-3124-9258
Abstract This research investigates a concept for cut-out resonators that exploit a small area of active mass of a host plate structure for sake of tuned, low frequency vibration attenuation. Integrated computational and experimental studies reveal that embedding the resonators at locations offering high bending moment gradient and arranging the central resonator beam along a nodal line of bending moment best excite the first resonator eigenmode for targeted vibration suppression. These results are independent of plate boundary conditions and do not require periodic resonators to achieve notable vibration suppression outcomes. These design concepts may guide the development of resonators for vibration absorption of plates with arbitrary boundary conditions.
Highlights Moment-coupled built-in resonators proposed. Computational and experimental studies demonstrate working mechanisms. Vibration attenuation of plates is functional regardless of plate boundaries. Absorption mechanism does not require periodic resonator placement.
