Bionic Design and Stress Field Analysis of Brake Disc’s Surface Micro-Structure

Abstract

The uneven friction of brake disk leads to the brake failure, which frequently results in serious traffic accidents. Based on the excellent wear-resisting properties of locust’s non-smooth surface structure, bionic brake disc with special surface micro-structure was designed. Utilizing ANSYS Workbench, the braking time and the stress distribution of both the bionic model and the smooth model during the whole process of brake under different initial velocity were analyzed. Compared to the smooth model, results showed that the braking time and contact stress decrease in a certain extent, indicating brake disc with special surface micro-structure exhibits relatively excellent braking performance and wear resistance. The results provided theories for exploring an optimization the method used to design brake discs with excellent braking performance and wear resistance.

Study of the effect of composite texture surfaces on brake friction squeal behavior

“…The inspiration for surface texture design stems from nature, where organisms exhibit geometrically non-smooth morphologies on their body surfaces. Through natural evolution, these organisms have evolved structural features that confer superiority and enhance adaptability to the environment [6][7] . However, the complexity of surface morphological structures in organisms lacks a unified research system to understand their mechanisms of action.…”
