The subject of elastohydrodynamic lubrication is identified with situations in which elastic deformation plays a significant role in the hydrodynamic lubrication process. To analyze the elastohydrodynamic lubrication (LEH) of elliptical contacts it is necessary to solve simultaneously the Reynolds equation for pressure and the elasticity equation. The greatest shortcoming of this approach is the dependence exponential between the viscosity and the pressure which is, so that the coupled equations system becomes highly nonlinear. The objective of this work is to analyze LEH in elliptical contacts by means of multi grid algorithms (used for modeling and simulating complex dynamic systems) to solve them.
