Abstract Misalignment is common in hydrodynamic journal bearings and the causes of it can be diversified, making lubrication performance exhibits stochasticity. Lubricant viscosity often heavily depends on temperature, which may vary during service result unexpected deviations. This article analyzes stochastic lubrications a cylindrical bearing with misalignment under uncertainties. The Reynold...

The equations of motion a rotor system mounted on journal bearings with non-linear characteristic are solved by high-precision analytical methods. A new technique has been developed for solving nonlinear differential systems bearings, taking into account nonlinearity reaction forces the lubricating layer. Algebraic were obtained that allow us to determine amplitudes oscillations and supports, c...
