AB - In this work, a representative mathematical model has been developed, which  reliably describes the heating and cooling of a journal bearing as a result  of its malfunctioning, and the model has been further confirmed on a test  bench. The bearing model was validated by using analytical modeling methods,  i.e. the experimental results were compared to the data obtained by  analytical calculations. The regression and variance analysis techniques were  applied to process the recorded data, to test the mathematical model and to  define mathematical functions for the heating/cooling of the journal bearing.  This investigation shows that a representative model may reliably indicate  the change in the thermal field, which may be a consequence of journal  bearing damage.
