A Reduced-Order Model for the Vibration Analysis of Mistuned Blade–Disc–Shaft Assembly
An effective reduced-order model is presented in this paper for the vibration analysis of a mistuned blade−disc−shaft assembly considering the flexibility of the shaft and the rotordynamic effects.

Optimization of cascade blade mistuning under flutter and forced response constraints [PDF]
In the development of modern turbomachinery, problems of flutter instabilities and excessive forced response of a cascade of blades that were encountered have often turned out to be extremely difficult to eliminate.

On the Beats of Mistuned Harmonic Consonances [PDF]
The present Paper forms a continuation of one presented to the Association a short time ago. The subject was first put prominently before the Association in Mr. Spottiswoode's Paper “On Beats and Combination Tones.” I subsequently showed some of the elementary experimental methods by means of which I attempted to deal with the questions raised.

Modelling and analysis of a high-speed turbine impeller concerning mistuning
As-manufactured impellers behave significantly different from nominal impellers. There are no identical blades due to geometric and material deviations.

Multistage Blisk Large Mistuning Modeling Using Fourier Constraint Modes and Pristine Rogue Interface Modal Expansion [PDF]
In the turbomachinery field, a great deal of research has focused on understanding the effects of mistuning on the dynamics of each stage. Mistuning in bladed disks is due to the blade to blade differences that typically occur due to manufacturing ...

Application of model updating techniques to turbomachinery rotor components
Model updating techniques are commonly used to improve simulation accuracy. Experimental data of component testing under laboratory conditions are normally used to improve analytical predictions of that component under operational conditions.

Listeners regularly judge the accuracy of musical performances. However, as is true for several types of judgments (e.g., beauty or obscenity), estimating the correctness of melodies is not based on a precise definition of the object/performance but ...

Nonlinear Vibrations of Low Pressure Turbine Bladed Disks: Tests and Simulations
One of the most effective methods to limit the mechanical vibrations of bladed disks is the use of friction damping at mechanical joint interfaces. Unfortunately, dedicated tests to assess the impact of mistuning and the effectiveness of friction dampers
