Originální abstrakt

The squeeze effect is an important subject in studies of elastohydrodynamic lubrication (EHL). By impact loading, the oil between point contact surfaces is entrapped at the central region or the peripheral region depending on the initial conditions. The effects of the loading process, surface roughness, and ellipticity ratio of contacts on the film thickness and pressure distributions are not fully understood yet. In the current study, those effects are elucidated through numerical analyses by specified initial impact gaps, which produce the central or the peripheral oil entrapments. The loading process, which can produce rather low pressure, has been proposed. Moreover, conditions, under which a microdimple is produced in the central circular bump are clarified.
