Research on Aerodynamic Damping of Bladed Disk With Random Mistuning [PDF]
, 2017 This paper presents an investigation on the aerodynamic damping of bladed disk (also called ‘blisk’) with mistuning. The study focuses mainly on the mechanism of the effect of random and intentional mistuning on the aero-elastic stability of blisk.

High order sensitivity analysis of a mistuned blisk including intentional mistuning
Journal of Theoretical and Applied Mechanics, 2017 Small deviations between turbine blades exist due to manufacturing tolerances or material inhomogeneities. This effect is called mistuning and usually causes increased vibration amplitudes and also a lower service life expectancy of bladed disks or so called blisks (bladed integrated disk).

Efficient computational techniques for mistuning analysis of bladed discs: A review [PDF]
, 2016 This paper describes a review of the relevant literature about mistuning problems in bladed disc systems, and their implications for the uncertainty propagation associated to the dynamics of aeroengine systems.

Reduced-Order Models of Blisks With Small Geometric Mistuning [PDF]
, 2017 A technique for generating reduced-order models (ROMs) of bladed disks with small geometric mistuning is proposed. Discrepancies in structural properties (mistuning) from blade to blade can cause a significant increase in the maximum vibratory stress ...

Nihon Kikai Gakkai ronbunshu, 2017 Although bladed disks of turbomachinery are nominally designed to be cyclically symmetric (tuned system), the vibration characteristics of all blades on a disk are slightly different due to the manufacturing tolerance, the deviation of the material ...

Research overview on vibration damping of mistuned bladed disk assemblies
Journal of Hebei University of Science and Technology, 2016 Bladed disk assemblies are very important parts in auto engine and gas turbine, and is widely used in practical engineering. The mistuning existing commonly in the bladed disk assemblies can destroy the vibration characteristics of the bladed disk ...
