       Abstract: The engineering surface is rough on microscopic scale. The contact behaviour between rough surfaces has a
       significant influence on various physical phenomena. Therefore, the method of contact modeling between rough surfaces
       has been a hot topic in the field of tribology for a long time. The GW statistical contact model proposed by Greenwood
       and Williamson is the most recognized rough surface contact model. The developments of rough surface contact model
       based on statistical analysis were reviewed in the present work. According to the improvements of the main defects of
       GW model, the research status of the statistical contact model was introduced. Some possible research hotspots of the
       statistical contact model in the future were summarized.
