面接触润滑条件下表面形貌对动压润滑的影响

利用课题组自主研发的面接触光干涉油膜厚度测量系统,对表面凹槽滑块的流体动压润滑油膜厚度进行了试验测量.试验中以静止的微型凹槽滑块平面和旋转的光学透明圆盘平面构成润滑副,且两润滑平面始终保持平行;在载荷固定的条件下,对油膜厚度—速度曲线进行测量.结果表明凹槽的宽度、深度、方向和位置等因素对油膜厚度有着重要影响.

Study on the Surface Morphology Effects on the Hydrodynamic Lubrication in Conformal Contact

This paper describes some experimental studies about the influences of grooved surfaces on the film thickness of hydrodynamic lubrication by a custommade test apparatus. In the experiments, the lubricated parallel contact consisted of a grooved micro-slider plane and a transparent glass disc. Under a fixed load ,the film thickness at different entrainment speeds was measured. The results show that the width,depth,orientation and position of the groove were the key factors to affect the film thickness.
