The present research considers the application of magnetorheological fluids as lubricants for journal fluid-film bearings. In order to solve an ever occurring problem of enhancing the performance of rotor machines to meet industrial requirements, a tribomechatronic system is proposed with a journal fluid-film bearing lubricated with a magnetorheological fluid. This type of fluids could be used as a direct actuator for a mechatronic rotor positioning system for rotor machines. As a part of a complex research on tribomechatronic bearings, the present research features a conceptual and a mathematical model of a journal fluid-film bearing that is lubricated with a magnetorheological fluid. The mathematical model is based on the Reynolds equation, and additional expressions take variable viscosity and presence of magnetic field into account. The paper features a two-step verification of the model based on comparison with experimental results by other researchers. It outlines certain peculiarities of the operation of fluid-film bearings lubricated with MRFs and sets directions for further research.
