Aspects of Coulomb Damping in Rotors Supported on Hydrodynamic Bearings,

Abstract

The paper is concerned with the effect of friction in drive couplings on the non-synchronous whirling of a shaft. A simplified model is used to demonstrate the effect of large coupling misalignments on the stability of the system. It is concluded that provided these misalignments are large enough, the system becomes totally stable provided the shaft is supported on bearings exhibiting a viscous damping capacity.
