Elimination of vibration localization in mistuned periodic structures
Journal of Sound and Vibration, 2005In this note, mistuned periodic structures are considered. Due to mistunings, some components of such structures may vibrate with small amplitudes, while some other components may vibrate with significantly large amplitudes. Such a behavior is known as vibration localization and is undesirable. To have a means of determining the occurrence of vibration

Forced Vibrations of Bladings With the Random Technological Mistuning
Volume 6: Structures and Dynamics, Parts A and B, 2010An approach has been considered for analysis of forced vibrations for randomly mistuned bladed discs. It is based on stochastic reduced basis method and hypothesis of locally distributed mistuning, which could realise in blade-to-blade joints due to the deviation at the assemblage technology.

The study at hand analyzes the influence of aerodynamic mistuning and aerodynamic coupling on the vibration behavior of mistuned small radial turbine wheels. The aerodynamic mistuning is caused by angular non uniformity of the variable turbine guide vanes.

Vibration of a mistuned bladed-disk assembly using structurally damped beams
AIAA Journal, 1998A model of a mistuned bladed disk is created and then analyzed for both free and forced vibrations. The model consists of structurally damped, Euler ‐Bernoulli beams connected at one end using springs. The model is useful in the prediction of the response of a turbine engine bladed disk in which only some of the blades have added damping.

The International Journal of Acoustics and Vibration
To ensure the working performance of mistuned blisks, a hybrid vibration reduction strategy using the material damping and intentional mistuning capacities induced by the hard coating was proposed here. For solving vibration characteristics of mistuned blisks deposited hard coating efficiently, a novel reduced-order model was established using the ...

Piezoelectric Networks for Vibration Suppression of Mistuned Bladed Disks
Journal of Vibration and Acoustics, 2006Extensive investigations have been conducted to study the vibration localization phenomenon and the excessive forced response that can be caused by mistuning in bladed disks. Most previous researches have focused on analyzing∕predicting localization or attacking the mistuning issue via mechanical tailoring.

Probabilistic Vibration Analysis of a Mistuned Integrally Bladed Disk
Advanced Materials Research, 2014Abstract. The objective of this paper is to probabilistically evaluate the effects of mistuned sectors on the dynamic characteristics of an integrally bladed disk (blisk). Small blade to blade physical variation in a disk is termed as mistuning. In this study, the dynamic characteristics of the perfectly tuned blisk were firstly analysed as a baseline.
