Abstract
Microstructured surfaces can reduce friction force between two contact pairs in relative motion under hydrodynamic contact. In this study, we evaluate the friction reduction performance of microdimpled surfaces with different cross-sectional profiles generated by nonresonant modulation cutting. Computational fluid dynamics simulation was conducted to simulate the friction reduction effect between surfaces with lubricants. An elliptical modulation texturing method is introduced based on a two-dimensional nonresonant vibration tool, which could generate adjustable high-frequency elliptical tool trajectories. Different dimpled surfaces were generated using three types of tool trajectories. Their influence on the friction reduction and load-carrying capacity were experimentally studied and evaluated by comparing the simulation and experimental results.
