... of NSV, but prevention measures are still lacking. This article addresses this by systematically studying the influence of aerodynamic and structural mistuning on NSV. This is achieved by incorporating mistuning effects in a validated linear model, in which individual blade modes are modeled as single...

... to blade mistuning, which can be characterized by the higher percentage of blades on the total blisk strain energy. All of the previous characteristics of mistuned bladed disks have to be regarded also during the design and test-phase of future aeroengine rotors. At this integrated bladed disks (blisks...

...Alejandro J. Rivas-Guerra, Assoc. Mem. ASME; Marc P. Mignolet, Fellow ASME This paper focuses on the determination and study of the maximum amplification of the steady state forced response of bladed disks due to mistuning. First, an optimization strategy is proposed in which partially mistuned...

... in a certain manner, causing localization of the mode and strong response in a particular blade. In addition, it is shown that the response of an intentionally mistuned system with maximum response does not change significantly when small random mistuning is added to the system. A method is described...

...D. M. Feiner; J. H. Griffin A new reduced order model of mistuned bladed disk vibration is presented. This new approach is shown to accurately represent the response of real turbine geometries when only a single family of modes is excited. Yet its mathematical form is even simpler than...
