| Summary: | Increasing high demands for concept design requires journal bearing to work under several operating condition. The purpose of this work is to study the effect of surface temperature on the performance of journal bearing for heavy duty machines. Steady state thermohydrodynamic model (THD) for journal bearings has been developed. The generalized Reynold's equation, energy equation in the oil film, and the heat transfer equation in the bush and shaft are solved simultaneously. It was found that the shaft temperature has a great effect on the performance of the bearing.
