Abstract
In order to explore the motion characteristics of the third body particle in the friction of the rough braking interface, based on W-M fractal theory and elastoplastic mechanics theory, the finite element model of the three body micro-extrusion shearing process of rough contact surface is established. The influence of the braking parameters on the motion characteristics of the single-particle third body is analyzed. The analysis results show that the three body contact steady state increases with the increase of brake pressure, and the shear speed affects the three body contact vibration. An increase in the friction factor accelerates the third body discharge friction gap to exacerbate the wear condition.Keywords
