Approaches to determination of the pressure distribution in the gap of long hydrodynamical bearings taking into account a dependence of the oil viscosity on pressure

Original language description

In computational models the fluid film bearings are usually accommodated by means of nonlinear force couplings. As the bearing gap is very narrow, a pressure distribution in the oil film can be described by a Reynolds' equation. Taking into account dependence of the lubricant viscosity on pressure, for its solution two approaches have been applied. The first one utilizes a finite difference method which arrives at solving a set of nonlinear algebraic equations ( Newton-Raphson method ). The second approach is based on application of a shooting method. For solving the initial problems the Euler method has been chosen.
