Investigation on vibration reduction performance of spiral acoustic black hole for ring-stiffened cylindrical shell

ObjectiveThis paper seeks to investigate the vibration reduction characteristics of a spiral acoustic black hole (SABH) on a ring-stiffened cylindrical shell and provide a new technical approach for the vibration reduction design of ring-stiffened cylindrical shells. MethodFirst, a finite element co...
