Abstract: A technique for generating reduced-order models (ROMs) of bladed disks with small geometric mistuning is proposed. Discrepancies in structural properties (mistuning) from blade to blade can cause a significant increase in ...

Abstract: An efficient methodology to predict the nonlinear response of bladed disks with a dry friction ring damper is proposed. Designing frictional interfaces for bladed-disk systems is an important approach to dissipate vibration ...

Abstract: A novel methodology to predict responses of bladed disks incorporated with a split ring damper is proposed. To account for the dynamic characteristics of a split ring damper, intentional blade stiffness mistuning is ...

Abstract: In operation, rotating bladed disks (blisks) are often subject to high levels of dynamic loading, resulting in large amplitudes of forced vibrations especially at resonance. Moreover, variations in structural properties ...
