摘要
求出了润滑副两表面反向运动 ,即滑滚比大于 2直至无限大的线接触热弹性流体动力润滑问题的完全数值解 ,揭示出这种润滑膜的几个特点 ,如表面的凹陷 ,随滑滚比的增加第二压力峰并入且逐渐增高压力主峰等 ,并讨论了温度
A full numerical solution is obtained for thermal elastohydrodynamically lubricated line contacts,of each contact the two surfaces are moving in opposite directions The sliding/rolling ratios are allowed to vary from more than 2 till the infinity Some characteristics of such films are revealed It is found that the contact surfaces can become concave,and that as the sliding/rolling ratio increases the pressure spike gradually merged into the main pressure peak meanwhile increasing the height of the latter The temperature viscosity wedge lubrication mechanism is discussed,too
