One of the common failure modes of the diesel engine turbochargers is high-cycle fatigue of the turbine-wheel blades. Mistuning of the blades due to the casting process is believed to contribute to this failure mode. A laser vibrometer is used to characterize mistuning for a population of turbine wheels through the analysis of the blade-response to ...

Capturing Mistuning Within Shrouded Integrally Bladed Disks With the Generalized Model of Mistuning
Volume 9: Structures and Dynamics: Structural Mechanics & Vibration; Supercritical CO2Abstract Bladed disks and blisks are designed to be cyclic structures that ideally have identical sectors. There will, however, always be mistuning, which is blade to blade differences that break the cyclic symmetry of the system and can result in an increase in vibrational amplitudes.

Flutter of Mistuned Turbomachinery Rotors
Journal of Engineering for Gas Turbines and Power, 1984An investigation of the fundamental aspects of flutter in mistuned turbomachinery rotors is presented. Perturbation methods are used to obtain asymptotic solutions to arbitrary order in the mistuning parameter. These solutions require only the knowledge of the eigensolution of the tuned system, and thus provide efficient formulas for calculating the ...
