Abstract

Under certain external unforeseen disturbances, the rotor-bearings' system exhibits self excited oscillating behaviours. The instability occurs when the speed exceeds a certain onset, appearing as self excited orbital motions induced by the fluid film dynamic forces. In this paper, an approximate closed form solution for the Reynolds’ equation for the particular case of the partial arc journal bearings in unsteady operating conditions, is proposed. The analysis considers the case of the incompressible coupled stress fluid under the classical hypothesis.
