摘　　要： 建立了微坑缸套表面润滑动力分析模型,获得了最大速度瞬时最小油膜厚度与球面微坑半径和微坑口部半径的关系方程,分析了球面微坑半径和微坑口部半径对最小油膜厚度最大瞬时值影响。数值结果表明,最大速度瞬时最小油膜厚度受到微坑口部半径的直接影响,是缸套表面油膜厚度的主要控制参数。 Lubricant dynamitic analysis model of micro-pit cylinder sleeve was presented, a relationship between the least lubricating film thickness on maximum velocity and the spherical radius of micro-pit, the top radius of micro-pit was established, the effects of the spherical radius of micro-pit and the top radius of micro-pit to the least lubricating film thickness on maximum velocity were analyzed. It is shown by numerical results that the least lubricating film thickness on maximum velocity is determined directly by the top radius of micro-pit, it is the main controlling parameter of film thickness of micro-pit cylinder sleeve.
