A single micro-convex body contact model is established based on the anisotropic fractal rough surface, and a rough surface contact model is established by combining an island distribution probability micro-convex body area distribution probability density function, so that a calculation method for the elastic-plastic contact stiffness of the anisotropic fractal rough surface is provided. According to the method, the vacancy of an existing anisotropic rough surface contact rigidity calculation method is effectively made up, the relation between the critical deformation amount and the micro-convex body grade and the influence o
