摘要：

The simulation of the non-stationary response of the journal bearings used in combustion engines plays a significant role in the bearing design process. Diverse simulation models contain various oil viscosity definitions taking pressure and temperature into consideration. However, viscosity dependence on the shear rate is often neglected. Within this paper, a bearing simulation model including the shear rate-dependent viscosity is described. The modified Cross equation was used to describe shear rate influence on viscosity. Numerical modelling of the main crankshaft bearing of a modern four-cylinder gasoline engine was performed. Selected calculation results were discussed and conclusions drawn. The modelling and calculation were carried out using the AVL software EXCITE (AVL LIST GmbH, Advanced Simulation Technology, Hans-List-Platz 1, Graz, Austria 8020).
