- СтавкаMATHEMATICAL MODEL FOR TEMPERATURE CHANGE OF A JOURNAL BEARING(Vinča Nuclear Research Institute, Belgrade, Srbija, 2018) Antunović, Ranko; Halep, Amir; Bučko, Mihael M.; Perić, Sreten R.In this work, a representative mathematical model has been developed, which re-liably 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 ex-perimental results were compared to the data obtained by analytical calculations. The regression and variance analysis techniques were applied to process the rec-orded 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.
