Abstract

Published experimental evidence reveals that foil bearings are prone to damage due to thermal runaway under certain operating conditions where thermoelastic instability sets in. This paper describes a methodology and a closed-form solution for prediction of the critical speed at which a foil bearing can become thermoelastically unstable. The theoretical predictions have been verified with several published experimental results. While the model pertains to a journal bearing-type configuration, it can be readily extended to other bearing configurations.
