Non-Contact Vibration Measurements of Mistuned Coupled Blades

Volume 4: Manufacturing Materials and Metallurgy; Ceramics; Structures and Dynamics; Controls, Diagnostics and Instrumentation; Education; IGTI Scholar Award, 1997
Most of the turbomachine manufacturers are using a non-contact measurement system to measure blade vibration by two probes located in the casing radially outside a blade row. All blades of a row can be observed by this system, therefore it may be considered to be an ideal solution for measuring the vibration response of mistuned blades which have quite

Random vibrations of mistuned periodic structures

2014
Nearly periodic structures exhibit localized modes of vibration depending upon the ex· tent of the coupling and the disorder between their periodic components. These localized modes may cause excessive vibration amplitudes resulting in significantly higher stresses than the ones the structures have been designed to withstand. The Rayleigh-Ritz method,

SLDV technology for measurement of mistuned bladed disc vibration

2008
Bladed discs are very sensitive structures and the amplitude vibration of each blade can vary significantly from blade to blade due to a series of factors such as geometrical inhomogeneity between blades or material properties. These factors lead to bladed disks mistuned thus the forced response amplitudes can be much higher than the level predicted ...
