通过理论分析和光干涉实验 ,考察了纯滑动热弹流润滑椭圆接触区内当卷吸速度与接触椭圆短轴成 0°和 45°角时出现的油膜局部增厚现象 ,即固体表面在接触区出现凹陷的现象 .解释了玻璃盘 -钢滚子接触副表面凹陷的形成原因 ,揭示了凹陷的深度、位置和形状随卷吸速度及接触椭圆短轴夹角的变化规律 .
Through theoretical analysis and optical interference experiments, the local thickening phenomenon of oil film when the entrainment velocity is at 0 ° and 45 ° to the short axis of the contact ellipse is investigated in the elliptical contact region of pure sliding thermal elastohydrodynamics, that is, the solid surface is in the contact region The reason of the depression of the contact surface between the glass disk and the steel roller is explained, and the variation of the depth, position and shape of the depression with the entrainment velocity and the angle of the short axis of the contact ellipse is revealed.
