Experimental Investigation of Mistuned Bladed Disks System Vibration
EXPERIMENTAL INVESTIGATION ONMISTUNEDBLADED DISK SYSTEM VIBRATIONbyJia Li Co-Chairs: Christophe Pierre and Steven L. Ceccio Bladed disks are critical structural components in jet engines and other turbomachin-ery. The nominal design for a bladed disk is typically assumed to have identical blades.However, there are always small, random variations in the blade properties d...
متن کاملForced response of mistuned bladed disks using reduced-order modeling
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 saving...
متن کاملUncertainty quantification in nonlinear structural dynamics for mistuned bladed disks
The recent improvements in turbomachinery design combined to the unavoidable requirements of kerosene savings require to analyze the exceptional operating regime of bladed disks, for which large deformations and large displacements can occur. It seems then quite appropriate to consider the geometrically nonlinear effects in the computational models dedicated to the analysis of mistuned turbomac...
