Vibrations of a Rotor under Combined Effects

Abstract

In chapter 7, we encountered the phenomenon that there is only a finite number of forward synchronous critical speeds of a shaft with uniformly distributed mass. In the light of the theory of flexural vibrations of a shaft, an infinite degree-of-freedom system, this phenomenon appears paradoxical. In section 8.2, an attempt will be made to overcome this paradox, by including the effect of shear deformation which is generally ignored in the theory of bending of beams and shafts.
