摘要
An experimental and numerical study was performed in this work to predict the squeal instability when pad specimens having different surfaces rotating on a brake disc specimen. The numerical results were consequently compared with the experimental results to investigate the effect of surface modification of pad materials on squeal generation. It was shown that surface modification of pad materials had a significant influence on the squeal instability. Diagonal grooved surface was found to be able to efficiently reduce squeal generation, which can be mainly attributed to its relatively smaller contact pressure distribution area compared to that of the smooth surface.
