Harmonic Mistuning of Blisks [PDF]
PAMM, 2015 AbstractThe paper describes a new method to calculate the maximum amplificationof blade vibrations of a bladed disk or blisk subject to manufacturing tolerances. Two effects of mistuned blisks are analyzed in this paper. The separation of two orthogonal nodal diameters are shown and described in detail.

Experimental investigations of the effects of mistuning on bladed disk dynamics.
, 2002 A bladed disk, such as a single stage of a turbomachinery rotor, is designed to be rotationally periodic. In reality, however, there are inevitably small differences between the blades, due to manufacturing tolerances, material defects, and uneven wear ...

International Journal of Rotating Machinery, 2000 This series of two papers focuses on the determination and clarification of the characteristics of the forced response of bladed disks that exhibit a mistuning pattern that is either harmonic or partial.

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 ...

Efficient computational techniques for mistuning analysis of bladed discs : a review [PDF]
, 2017 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.

A Modified Nonlinear Modal Synthesis Scheme for Mistuned Blisks with Synchronized Switch Damping
International Journal of Aerospace Engineering, 2018 In the authors’ previous work (MSSP 2017), we show that the synchronized switch damping based on negative capacitor (SSDNC) is a good candidate for vibration suppression of tuned blisks.
