Abstract

The present work deals with analysis of a uniformly spinning shaft with a non-central disc mounted on a rotating (precessing) base, where the spin axis and the precession axis intersect at right angle. The motion of the rotor is such that it undergoes small elastic deformation superposed on rigid body rotation about a point. It is assumed that the shaft is axially and torsionally stiff and the disc has four degrees of freedom. Due to unbalance excitation, somewhat like a rotor on an orthotropic support, this rotor has also been found to undergo backwardwhirl.
