The present work describes a theoretical study to demonstrate the effect of the journal misalignment on the performance of an orifice compensated hole-entry hybrid journal bearing system lubricated with ER fluid. The journal misalignment has been accounted for by defining a pair of misalignment parameters sigma and delta. Continuous Bingham Model has been used to describe the behavior of ER fluid. The bearing static and dynamic characteristic parameters presented in the study indicate that the effect of journal misalignment is in general to cause a reduction in bearing dynamic characteristic parameters whereas the electric field in the ER fluid is to partially compensate this loss.
