Studying for the crankshaft-bearing system of a diesel engine in this paper, using the software of AVL-EXCITE set up the coupled multi-body dynamics simulation system of the crankshaft and bearings, the characteristics of oil film on main bearing were analyzed when the crankshaft under different impact loading. While, taking full account of the speed and the clearance of bearing impact on the lubrication performance of bearing .Working out the changes of main bearing’s minimum oil-film thickness and maximum oil-film pressure with crank angle and the orbits of the main-journal center. By studying of the impact stiffness of the bearing’s oil film to export the contact between the crankshaft and the body, and lay the foundation for building the whole diesel engine model and the assessment of impact and the optimal design, so as to further improve the impact resistance of the diesel engine .which has great significance to improve the vitality of the diesel engine.
