Based on statistical model,the calculation model of hybrid lubrication and wear of textured bearing was established.By generating virtual rough surface of bearing bush,the average flow Reynolds equation,K-E elasticplastic contact model,Boussinesq integral and Archard wear equation were used to solve oil film pressure,rough peak contact pressure,elastic deformation of bearing bush and shaft,and abrasion on tile surface respectively.The finite difference method and Newton downhill method were used to solve the model of hybrid lubrication and wear,and the oil film pressure,rough peak contact pressure,elastic deformation of bearing bush and shaft,and abrasion on tile surface at different eccentricities were obtained.The calculation results were compared with those of other mixed lubrication models,and the validity of the model was verified.Taking circular pit texture as an example,the effects of lubrication state transformation and texture on wear process under various working conditions were studied.The results show that texture can form secondary lubrication,which is beneficial to fluid lubrication.With the increase of eccentricity,the loadcarrying capacity and rough peak contact load are increased rapidly,and the inflection point of friction coefficient appears.In the mixed lubrication state,the surface texture will reduce the loadcarrying capacity and increase the wear in the early stage of wear process,while with the further wear of sliding bearings,the surface texture can play a role in reducing wear.
