The knowledge of dynamic parameters of journal bearing is crucialfor the accurate determination ofthe critical speed of a shaft and also for studying the stability ofthe journal bearing itself. These parameters can be determined from the solutions of Reynolds equation numerically using successive over relaxation (SOR) technique. The optimum over relaxation factor was found using a quadratic formula and only one convergence limit had to be satisfied before terminations of the iteration procedure, thus shortening the overall computing time. Results obtained are comparable with at least 90% of accuracy to other researches. This shows that SOR can accurately and effectively predict the stability of a journal bearing. ©2008 IEEE.
