摘要：The heating and mechanics effects due to the temperatures and pressures in bearings were largely studied these last years but separately; few studies are devoted to the two phenomena acting together in dynamic mode, such as the crankshaft and rod bearings; where the requirements are very severe. In order to approach reality and confronting with other studies being interested in the thermo-elastohydrodynamic phenomena (TEHD). The studied model takes into account the deformations due to the pressures field for the bearing as well as the dilation effect and the reduction of the lubricant viscosity, due to the heat transfer effect, between oil and bearing. Simulation results of the crankshaft bearings of in internal combustion engine are presented and show that the thermal distortion has remarkable effects on the bearings performances.
