Vibrations of Twisted Rotating Blades

Journal of Vibration and Acoustics, Transactions of the ASME, 1984
The literature dealing with vibrations of turbomachinery blades is voluminous, but the vast majority of it treats the blades as beams. In a previous paper a two-dimensional analytical procedure was developed and demonstrated on simple models of blades having camber.

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.

On the stability of rotating blade arrays

Journal of Sound and Vibration, 2004
Abstract A mathematical model consisting of an array of rotating pendulums was built to study the stability of an array of rotating blades and the dynamic interaction between the blades and the rotor. This model can be solved in closed form, yielding some general results regarding the stability of the system, particularly for the effects of the blade–

Untwist of Rotating Blades

Journal of Engineering for Power, 1975
This paper deals with the deformation and the stress of an axial flow compressor rotor blade under the loading of centrifugal forces. Coupled deformation of extension, bending, torsion and transverse shear of a pretwisted curved bar with arbitrary cross section is considered.
