Abstract
An analytical model for the textured infinitely long slider is developed to study the influence of cross-hatched texture on hydrodynamic lubrication by considering the mass-conserving boundary condition. The three-dimensional morphology of the cross-hatched texture is characterized by a series of mathematical formulas. By using multigrid method and Gauss–Seidel iteration, the hydrodynamic pressure distribution of textured surface can be obtained to analyze the influence of width, depth, spacing, cross-hatched angle and overlapping coefficient of the cross-hatched texture on the hydrodynamic lubrication. The results show that hydrodynamic lubrication can be generated between two parallel plane surfaces with cross-hatched texture. Moreover, the geometrical parameters of the cross-hatched texture have prominent effect on hydrodynamic pressure distribution and load carrying capacity.
