Abstract

A time-dependent mathematical model for the conforming shell gas journal bearing is presented. A computational simulation of the mathematical model is used to investigate the dynamic behaviour and steady state characteristics of the bearing. The onset of dynamic instabilities, violation of the minimum film thickness criteria and component separations are found to be the three factors which form upper and lower bounds on the range of acceptable loads.
