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 condition.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 starvation.
