VIBRATORY LOCALIZATION OF MISTUNED BLADED DISK ASSEMBLIES ──A REVIEW

This paper reviews the state of the art in the vibratory localization of mistuned bladed disks in the past three decades with regard to modal localization and response localization. Blade-to-blade variations (called as mistunings) in their geometry and structural properties occur during the manufacturing process and/or as a consequence of in-service wear. Although small under certain conditions they may localize the vibratory mode and confine the response to a region near the source. Since mistunings can re...
