Abstract

A reduced-order model formulation is presented for examining the forced response of tuned and mistuned bladed disks. The technique developed uses modal information obtained from highly detailed finite element models to create, in a systematic manner, much simpler and computationally inexpensive models of bladed disks. The small size of the reduced-order model and associated computational savings enable analysts to examine the effect of mistuning strength and pattern, interblade coupling, and localized modes on forced response amplitudes. Previously, this was a formidable task with finite element modeling for even a single mistuning pattern.
