Abstract:

This report treats the theory of the stability of an elastic rotor. It covers such effects as instability caused by friction damping in the rotor, instability caused by shaft asymmetry, instability caused by asymmetry of the rotor mass, instability induced by fluid film journal bearings, the effect of static damping on the stability of the rotor, the influence of gyroscopic effects, the effect of flexible bearing supports, and the effect of gravitational and unbalance forces. The report gives the basic governing equations and the methods of their solution. The conditions are established under which instability is encountered and it is shown how the results relate to a practical rotor system.
