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,随滚滑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-粘度楔润滑机理。

Abstract: 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.

Key words: Sliding/rolling ratio, Temperature-viscosity wedge, Thermal elastohydrodynamic lubrication, Ultrasonic honing Cavitation effect Test analysis
