A reduced order model based on sector mistuning for the dynamic analysis of mistuned bladed disks [PDF]

International Journal of Mechanical Sciences, 2011
In this paper, a pre-existing reduction technique suitable for the analysis of mistuned bladed disk dynamics, the Component Mode Mistuning technique (CMM), originally developed exclusively for the use of blade frequency mistuning pattern, is extended in order to allow for the introduction of a sector frequency mistuning pattern.

Exploration of blade detuning tests for mistuning identification of blisks

Mechanical Systems and Signal Processing, 2022
This paper presents a novel blade mistuning identification method based on blade detuning tests. Blade detuning tests consist of blade-by-blade impact testing in a blisk with detuning masses purposefully attached on all the blades except the one ...

Damping mistuning effect of the hard-coating-based intentional mistuning techniques on mistuned blisks and its mechanism

Aerospace Science and Technology, 2020
Abstract Intentional mistuning based on damping hard coatings can realize a combination of intentional mistuning and a substantial increase in the damping of the system, but causes damping mistuning. Aiming at figuring out the specific effects of damping mistuning, this paper conducts investigations of vibrational characteristics of mistuned blisks ...

A New Mistuning Form in Periodic Structure - Force Mistuning

Advanced Materials Research, 2012
The mistuning of periodic structure was generally considered to be natural parameter mistuning, such as stiffness mistuning, damping mistuning and mass mistuning. However, in engineering practice, there was another kind of mistuning——force mistuning, which has not been studied yet.

Control of mistuning level using hard coating for blisks based on mistuning identification technique

Aerospace Science and Technology, 2021
Abstract Mistuning will lead to vibration localization of blisk, which seriously affects the service life of blisks. To control the mistuning level of blisks, a novel control method using hard coating is proposed. In this method, the thickness of hard coating is designed according to mistuning state of blisk substrate, so that, the mistuning level ...

A New Mistuning Form Existed in Periodic Structure-Force Mistuning

Applied Mechanics and Materials, 2012
The mistuning of periodic structure was generally considered to be natural parameter mistuning, such as stiffness mistuning, damping mistuning and mass mistuning. However, in engineering practice, there was another kind of mistuning—force mistuning. Based on a typical concentrated parameter model of periodic structure, the vibration characteristics ...

Analysis of mistuned cyclic systems using mistune modes

Applied Mathematics and Computation, 1995
The bladed disk assembly, a prime example of a cyclic system, forms an important component of modern turbomachinery. Vibration of the blades leads to fatigue damage and limits their service life. Analysis of these systems is complicated by the combination of coupling of blade dynamics with mistuning of the blade properties.
