| Abstract Scope |
In metal forming of automotive parts, friction between the tools and sheet metal largely affect the formability of sheet material, tool life and surface finish of final product. Tool surface functionalization by texturing would be more economically feasible for improved tribological conditions. The aim of the present work is to establish theoretical background for the frictional behavior of textured surfaces under hydrodynamic lubrication. In this study, by utilizing the three-dimensional computational fluid dynamics (CFD) simulation, the lubrication model of a friction pair with micro-dimple array was established based on the Navier–Stokes equations. In order to optimize the tribological performance with different surface texturing parameters such as four different textured surface geometries, texture densities and three different textured patterns on the frictional behavior of textured surfaces, 3D simulations are performed for a given lubricant. Numerical simulation results are discussed in light of the experimental investigations. |
