The paper presents a new efficient computational model of a slide bearing. The slide bearing computational model is used as a submodule of the powertrain model. A complex computational model of a powertrain, a virtual engine, is a powerful tool for the solution of structural, thermal and fatigue problems. The virtual engine results have to give answers to different questions, mainly those concerning the area of noise, vibrations and component fatigues. The paper includes a description of fast algorithm for a hydrodynamic solution of a slide bearing incorporating pin tilting influences. The hydrodynamic problem solution incorporates variable multigrid strategies. This approach enables a fast solution of the powertrain model including tens of slide bearings.
