Abstract

The brake is a crucial automotive safety component, and the persistent brake squeal noise significantly impacts passengers' long-term riding experience. Utilizing a non-smooth textured surface enhances the tribological behavior of the interface, offering a novel solution to address brake friction squeal. In this study, we design a brake disc with a composite structured surface, modeled using ABAQUS and analyzed through complex eigenvalue analysis. Results indicate that the composite textured surface disc, compared to its smooth counterpart, exhibits a smaller tendency for unstable vibration and a larger negative damping ratio. This highlights its heightened efficacy in mitigating brake friction squeal behavior.
