Abstract
A novel approach for reducing mode localization of bladed-disk assemblies in turbomachinery is presented .A virtual shroud is created with piezoelectric coupling to reduce the sensitivity of the compressor disks to model localization. Both direct and resonant shunts are evaluated using a simple lumped-mass model. Resonant shunts are shown to be effective in reducing localization of certain structural modes.
