Abstract: The parametric vibration and combined resonance of a turbine blade with a preset angle subjected to the combined effect of parametric and forced excitation were investigated. The blade was modeled as a rotating beam ...

Abstract: A rotating thin blade with bend-torsional coupling subjected to vortex induced vibration (VIV) is considered in this paper. It is necessary to study the motion coupled bending torsion due to the discordant centroid and ...
