The surface roughness effects on the dynamic squeezing behavior of a finite length partial journal bearing under a time dependent oscillating load is studied. Use Christensen's stochastic models to develop the stochastic Reynolds' equation of the longitudinal, transverse and uniform isotropic roughness. According to the results obtained, the roughness(More)
