Abstract： In order to solve the problem of sliding bearing oil film thickness field，temperature field and pressure field of visualization，the OpenGL graphic technology was applied to the oil film of sliding bearing characteristics of three-dimensional model of the display，the hydrodynamic sliding bearing oil film characteristics of 3D visual simulation system was researched and developed. The model was simplified to omit bearing thickness cylindrical surface to handle. For ease of observation，the thickness field，temperature field and pressure field based on bearing curved was built in the outer surface，the "high+color" combination method was used to show the characteristics of oil film parameter，the specific method of establishing model was given， model scaling，rotating through the man-machine interactive mode control，a model of rotation，scaling scheme was given. The research results show that simulation system realizes the observation analysis and interactive operation of fluid dynamic pressure radial sliding bearing oil film visualization model，can conveniently，visually research the bearing oil film performance，contribute to the sliding bearing fault analysis so as to improve the quality of design.
