摘　　要：综合考虑轮齿在不同啮合点处的曲率半径、卷吸速度、轮齿载荷随时间的变化 ,考虑压力对流体粘度和密度的影响 ,利用多重网格技术求得齿轮非稳态弹流润滑的完全数值解。A full transient elastohydrodynamic lubrication solution of an involute spur gear was obtained by utilizing the multigrid method, which takes into account the variation of equivalent curvature, entertainment velocity and load on time along the line of action, without the lubricant thermal and rheological effects. The influences of load spectrum, where the load was carried by one pair of teeth and two pairs of teeth repeatedly, and impact load when the teeth come into action on the elastohydrodynamic lubrication were analyzed as well.
