主　　题：Hydrodynamic lubrication Tribological characteristics Surface texture 

摘      要：The research on surface texture is developing from single macro-texture to composite micro-nano *** current research on the anti-friction mechanism and theoretical models of textures is relatively *** the characteristics of different types of surface textures and determining the applicable working conditions of each texture is the focus of current *** this paper,a mathematical model of hydrodynamic lubrication is established based on Navier-Stokes *** FLUENT software is used to simulate and analyze the four texture models,explore the dynamic pressure lubrication characteristics of different texture types,and provide data support for texture *** key variable values required by the mathematical model are obtained through the simulation *** friction coefficient of the texture under different working conditions was measured through friction and wear experiments,and the mathematical model was verified by the experimental *** research results show that circular texture is suitable for low to medium speed and high load conditions,chevron texture is suitable for medium to high speed and medium to high load conditions,groove texture is suitable for high speed and low load conditions,and composite texture is suitable for high speed and medium to high load *** the experimental results with the results obtained by the mathematical model,it is found that the two are basically the same in the ranking of the anti-friction performance of different textures,and there is an error of 10%−40%in the friction coefficient *** this study,a mathematical model of hydrodynamic lubrication was proposed,and the solution method of the optimal surface texture model was determined.
