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 ...

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 ...

Optimization of Intentional Mistuning Patterns for the Mitigation of the Effects of Random Mistuning

Journal of Engineering for Gas Turbines and Power, 2014
This paper focuses on the optimization of intentional mistuning patterns for the reduction of the sensitivity of the forced response of bladed disks to random mistuning. Intentional mistuning is achieved here by using two different blade types (denoted as A and B) around the disk.

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.
