By selecting the pindisk experimental model and cylindrical surface texture as the object of study, the friction coefficient of surface texture and the wear loss of disk specimen were measured by experiments, the maximum film surface pressure was got by unit simulation methods. The correlation coefficient was introduced to study the correlation between friction coefficient and wear loss with maximum film surface pressure. The results show that there is quite high correlation between the maximum oil film pressure obtained by numerical analysis with the friction coefficient and wear loss measured by experiments. Unit simulation analysis method can reflect the overall trend of lubricating and antifriction properties of surface texture, which can be used to determine the optimized parameter range of surface texture and is an effective method of reducing the experiments. But the method is not suitable to use when the diameter of surface structure is quite small.
