摘　　要：针对主轴承,建立了含油膜润滑的曲柄连杆机构动力学模型,建立了曲轴主轴承的耦合模型,得到了曲轴轴心轨迹曲线,最小油膜厚度。同时分析了发动机转速、温度及轴承间隙对轴心轨迹和油膜最小厚度的影响。For the main bearings, a dynamic crank train of the model with oil film hydrokinetics and coupled model of main bearing were established. Based on those two models, crankshaft center movement curve and minimum oil film are obtained. Meanwhile, the effects of engine speed, oil temperature and bearing clearance on the crankshaft center movement and minimum oil film are analyzed.
