Abstract:	Surface texture technology is an effective means for reducing friction and wear. By correlating three-dimensional topography parameters with texture design parameters, the variation trend of surface tribological properties can be intuitively revealed, which is more convenient for the texture topography design. This study selects five three-dimensional topography parameters specified in ISO 25178 and systematically explores the correlations between three-dimensional topography parameters and surface friction characteristic by analyzing the influence of texture design parameters, which can provide a reference for the surface topography design of elastohydrodynamic lubrication interfacial texture. The dual-objective optimization framework aims to simultaneously maximize the maximum positive pressure and minimize the friction coefficient, utilizing texture design parameters as design variables. Finally, the results are verified by experiments. The results show that the optimized textured surface should have a larger negative Ssk, a smaller Sku, a larger Vvv, a smaller Smr1 and a smaller Smr2. The test results show that the optimal textured surface has better friction characteristics in the actual friction environment. [ABSTRACT FROM AUTHOR]

Abstract:	Surface texture technology is an effective means for reducing friction and wear. By correlating three-dimensional topography parameters with texture design parameters, the variation trend of surface tribological properties can be intuitively revealed, which is more convenient for the texture topography design. This study selects five three-dimensional topography parameters specified in ISO 25178 and systematically explores the correlations between three-dimensional topography parameters and surface friction characteristic by analyzing the influence of texture design parameters, which can provide a reference for the surface topography design of elastohydrodynamic lubrication interfacial texture. The dual-objective optimization framework aims to simultaneously maximize the maximum positive pressure and minimize the friction coefficient, utilizing texture design parameters as design variables. Finally, the results are verified by experiments. The results show that the optimized textured surface should have a larger negative Ssk, a smaller Sku, a larger Vvv, a smaller Smr1 and a smaller Smr2.
