Blade-Tip Timing Measurement Of Synchronous Vibrations Of Rotating Bladed

, 2002
Blade-tip timing (BTT) is a promising method for the detection, measurement and analysis of blade vibrations in rotating bladed assemblies. However, the intricacies of the method when applied to real rotating structures undergoing synchronous (Engine Ordered) vibrations are not yet fully understood.

Non-linear flapping vibrations of rotating blades

Journal of Sound and Vibration, 1982
Summary: The nonlinear equations of motion of a rotating blade undergoing extensional and flapwise bending vibrations are derived, including nonlinearities up to 0(e3). The strain-displacement relationship derived is compared with expressions derived by earlier investigators and the errors and the approximations made in some of those are brought out ...

Dynamic Response of a Rotating Blade with Time-Dependent Rotating Speed

Journal of Sound and Vibration, 1993
Abstract The general vibration of a rotating blade with time-dependent angular speed is investigated in this paper. A simple plate model is used to represent the blade, and its angular speed is characterized as a small periodic perturbation superimposed on a constant speed.
