采用光干涉实验技术研究间歇运动条件下，充分供油、中度乏油和严重乏油3种供油条件对弹流润滑油膜的影响。结果显示，在其他条件一致情况下，中度乏油只是在减速和加速阶段对油膜厚度和形状有影响，在停歇阶段，油膜变化与充分供油条件下的油膜变化情况一致；在严重乏油条件下，在减速和增速区间，速度对膜厚的变化基本无影响，在停歇阶段严重乏油也会造成油膜的明显降低。

The influence on elastohydrodynamic lubrication film in intermittent motion by oil supplied condition,such as fully supply,middle starvation and heavy starvation,was studied with optical interferemetric experiments.The results show that,if other conditions remain the same,middle starvation only has an effect on oil film thickness and shape in the stages of deceleration and acceleration;in the intermittent period,its film variation coincides with that in the fully supplied condi?tion.In the heavy starved condition,entrainment velocity hardly exerts an influence on the variation of oil film in the stages of deceleration and acceleration.The film thickness is decreased obviously in the intermittent period because of heavy star?vation.
