本文介绍了纯滚动弹流体动力润滑 (EHL) 接触中油滞留（或冲击凹坑）运动的研究。通过将钢球撞击润滑的玻璃盘来形成油截留。然后在纯滚动条件下激活接触，并通过光学干涉测量法观察夹带油的运动。研究发现，在EHL接触内凹坑运动过程中，凹坑核心的位移存在一个临界值。当凹坑芯的位移小于临界值时，凹坑以夹带速度移动，并且凹坑芯的膜厚度几乎保持恒定。当位移超过临界值时，韧窝速度减慢，深度迅速减小。从理论上和实验上研究了速度、初始凹坑深度、载荷和初始间隙尺寸等影响因素的影响。
This article presents a study on the movement of an oil entrapment (or impact dimple) in a pure rolling elastohydrodynamic lubricated (EHL) contact. The oil entrapment was formed by impacting a steel ball against a lubricated glass disc. The contact was then activated under pure rolling conditions, and the movement of the entrapped oil was visualized by optical interferometry. It was found that during the movement of the dimple within the EHL contact, there exists a critical value for the displacement of dimple core. For the displacement of the dimple core less than the critical value, the dimple moves at the entrainment velocity and the film thickness of dimple core remains almost constant. For displacement beyond the critical value, the dimple slows down and its depth decreases rapidly. The effects of influential factors such as speed, initial dimple depth, load, and initial gap size were theoretically and experimentally investigated.
