In order to study the effect of the elastic material with surface micro-textures on the cavitation phenomenon and lubrication characteristics of friction pair,an elastic texture 2D calculation model considering cavitation effect was established,and the fluid-solid coupling method was used to calculate the interaction between the lubrication flow field and material deformation.Compared with the rigid material with textures,the influence of elastic material with textures on the lubrication performance of the friction pair was analyzed in terms of elastic modulus,sliding velocity,texture depth and texture spacing.The accuracy of the simulation results was verified by experiments.The results show that elastic texture friction pairs have smaller friction coefficient and better lubrication performance than rigid texture friction pairs.There is an optimal texture depth,which makes the friction force of the elastic texture friction pair minimum and the bearing capacity maximum.The increase of sliding speed and texture spacing can improve the lubrication performance of elastic friction pair.With the decrease of the material elastic modulus,the elastic deformation and the oil film thickness increase,cavitation phenomenon becomes more significant,and the lubrication performance of the friction pair is improved.
