| Abstract: | Based on muti -body dynamics method, the elastic hydrodynamic model is established to analyze the lubrication characteristics of the big - end bearing of the connecting rod of a gasoline engine. The parameters are calculated and analyzed in details, including total peak pressure, peak asperity contact pressure, minimum oil film thickness, mean friction power loss and so on. The results show that the lubrication state of the big - end bearing is acceptable and satisfactory. |
