摘　　要：应用多重网格技术,求得齿轮非稳态弹流润滑问题的完全数值解。分析了冲击载荷对齿轮弹流润滑的影响。在冲击载荷作用下,得到轮齿的摩擦因数、两轮齿接触点中心压力、中心膜厚、最小膜厚的变化规律,对分析齿轮传动问题具有重要意义。A complete numerical solution for the transient elsatohydrodynamic lubrication problem of an involute spur gear was obtained by using simplified muhigrid method. The influence of impact load when the teeth come into action on the elsatohydrodynamic lubrication was analyzed as well. It also reveals that the change of the friction coefficient, central pressure and central film thickness. It is important to the analysis of spur gear.
