Thermoelastic behaviour of journal bearings undergoing seizure

Extensive numerical results are presented for the behaviour of journal bearing undergoing seizure. Included in the results is a sensitivity study performed to investigate the influence of various bearing parameters and operating conditions on the onset of seizure. It is demonstrated that high shaft speeds could lead to a very rapid seizure when the bearing is subjected to dry sliding. The significance of housing flexibility, internal cooling, and heat conduction through the contact between the shaft and bearing are discussed in depth.
