Analysis of lateral vibrations of rotating cantilever blades allowing for shear deflection and rotary inertia by reissner and potential energy methods

Abstract The lateral vibrations of a uniform rotating blade have been analysed applying the Reissner and the potential energy methods. Shear deflection and rotary inertia are taken into account. A convergence study of the two methods is made and the effects of shear deflection, rotary inertia, rotation and stagger angle on the blade vibration characteristics are discussed. Comparison of the results indicates a quicker convergence and better mode shapes by the Reissner method than the classical potential energy method.
