| Abstract:Based on Reynolds equation, numerical analysis was carried out on the oil flow in main bearings of diesel engines, and the characteristics and pressure distribution of oil flow in main bearings under different oil pressure are obtained. Based on oil system test bench, the main bearing scale model test was carried out to verify the accuracy of the numerical simulation method. The test results show that the numerical calculation results coincide well with the scale model test results, thus verify the correctness of the scale model test, which offer theoretical and experimental foundation for further research on diesel engines’ main bearing lubricating technology. |
