Simulation of the thermal process and friction diagnostics in a system of nonlubricated sliding bearings on a common shaft

Abstract

The development of a method of thermal diagnostics of friction allowing evaluating friction torque in a system of sliding bearings on a common shaft by temperature data under the assumption of uniform temperature distributions on the cross section of a shaft and along the length of bearings in the case of dependence of thermal properties of materials on temperature is described. The resistance of the obtained solutions to errors in temperature data is shown.
