Squeeze Film Bearing for the Elimination of Oil Whip

Abstract

In this paper we demonstrate that with sufficient external damping the bearing instability known as oil whip, commonly observed in rotating systems, can be eliminated. However, the amount of external damping required to alter the undamped case is prohibitive. This leads to the development and analysis of a mathematical model for a squeeze film bearing. We show that it can supply the necessary external dissipative force required to eliminate the oil whip phenomenon.
