Performance of EHL Oil Film in Intermittent Motion

In this paper, the variations of the squeeze elastohydrodynamic lubrication (EHL) oil film in unidirectional and bidirectional intermittent motions are investigated theoretically. For the unidirectional intermittent motion, the effects of stop time, deceleration, elliptical ratio and applied load ar...
