本文提出了一种新的实验技术，利用光学干涉测量法直接测量弹性流体润滑条件下油膜的非牛顿响应。采用步进电机驱动玻璃盘或钢球，产生沿运动方向厚度波动的月牙形厚油膜。试验分别在纯滚动和纯滑动条件下进行。已经发现，EHD接触中的油表现得像固体一样，并且在接触表面或接触表面附近滑动。
A new experimental technique using optical interferometry has been developed to obtain a direct indication of non-Newtonian response of an oil film under conditions of elastohydrodynamic (EHD) lubrication. A glass disk or a steel ball has been driven by a stepping motor so that crescent-shaped thick oil films with undulation in thickness along the direction of motion have been generated. The experiments have been carried out under pure rolling and pure sliding conditions. It has been found that the oil in an EHD contact behaves like a solid and slips at or near the contact surfaces.
