Abstract
The effects of coupling torsional flexibility on the vibrations of rotating blade are investigated in this study. A mathematical model that accounts for the coupling torsional deformations, blade bending deformations and the system rigid body rotational motion is utilized. The lagrangian dynamics is used in deriving the equations of motion, within the assumption of small deformation theory. The blade flexibility is discretized using the finite element method. Furthermore, the effects of axial shortening as well as the effects of gravity are included in the model. Numerical simulations show that the coupling torsional flexibility plays an important role in the dynamic behavior of rotating blades.
