Based on the finite element software ABAQUS,finite element models of the friction process of a car front axle rocker bushing with flexible surfaces similar to the head surface of the dung beetle are established and their friction characteristics are verified.By selecting an appropriate hyperelastic constitutive model and changing the size of the convex hulls on the surface of the bushing,the variation law of the radial and torsional mechanical properties of the flexible friction pair are analyzed.It turns out that the design of bionic convex hulls changes the maximum stress and strain positions of the bushing under stress,then it can effectively prolong the service life of the rubber bushing surface;the contact friction force and friction coefficients of the bionic bushings surfaces are obviously reduced,the friction reduction and wear resistance of the type2 model surface is the best.
