In order to study the effect of the morphology parameters of the T-shaped groove-shaped non-smooth surface on the friction performance,the wear resistance of the self-assembled pit-shaped non-smooth surface was verified.Based on the steady-state two-dimensional incompressible Reynolds equation,a theoretical model of T-groove surface texture was established; the finite difference method and the Gauss-Seidel iteration method were used to solve the oil film pressure distribution and shear stress on the metal surface,thus the oil film bearing capacity and friction factor were obtained; the influences of the width coefficient ratio α and depth coefficient ratio β of the T-slot texture on the oil film bearing capacity and friction coefficient of the metal-rubber friction pair had been numerically analyzed.The results show that the existence of T-shaped groove texture increases the pressure inside the oil film,and with the increase of T-groove width coefficient ratio,the dynamic lubrication performance of the texture first increases,then decreases and then increases，when the width factor ratio is 40%, the best hydrodynamic lubrication performance is achieved,and the larger the width factor ratio is,the worse the dynamic pressure effect of the texture is;when the width factor ratio is close to 1,the groove becomes a rectangular groove abruptly,which increases the dynamic pressure effect; as the T-groove depth coefficient ratio increases,the texture dynamic lubrication performance first increases and then decreases,and the width coefficient ratio is the best in the range of 40% to 60%; within the range of hydrodynamic lubrication,appropriately controlling the width ratio and depth ratio of the T-groove,making the bottom of the groove as flat as possible,ensuring good synergy and dynamic pressure area between the upper and lower parts of the texture,T-groove surface texture with the best lubrication and friction performance can be obtained.
