Abstract
It is proved that the optimal design of surface textures (positive or negative) improve the lubrication performance by generating extra hydrodynamic pressure at the interface of the sliding pairs. In the present work, the effect of various positive surface textures on hydrodynamic performance of parallel sliding contact under mixed lubrication is researched. The modified Reynolds equation and asperity contact model are solved simultaneously to assess the hydrodynamic pressure and minimum film thickness for different shape of textures. The results depict that elliptical shaped texture generate high hydrodynamic pressure as well as minimum film thickness at the conjunction than the other texture shapes.
