LONGITUDINAL MAGNETIC FIELD IN THE JOURNAL SLIDING BEARING GAP
Journal Title: Tribologia - Year 2011, Vol 240, Issue 6
Abstract
In this paper, the authors present analytical and numerical modelling of the components of the vector magnetic field’s induction in the journal sliding bearing gap. This issue becomes important when a lubricating agent containing a ferro-fluid in the journal sliding bearing gap is applied which affects the external magnetic field. Modelling components of the vector magnetic field’s induction is based on the analytical derivation of general solutions of Maxwell's equations, then the determination of the constants of the integration are made by computer simulation. So numerically calculated magnetic field to be used for further numerical calculations include hydrodynamic pressure distribution and friction forces in the journal sliding ferro-fluid lubricated bearings. The paper also presents the geometry of the sliding bearing with a coil that produces an external stationary magnetic field.
