The influence of surface topography on friction squeal-A review

Friction squeal is an unstable friction-induced vibration with high frequency and high intensity, which is troublesome for both people and environment. Surface topography is an important influencing factors of friction squeal. In this paper, based on introduction of surface topography, a review on the influence of surface topography on friction squeal is conducted from the aspect of experimental analysis, theoretical research and simulation analysis. For the convenience of scholars’ understanding and carrying out relevant research, the influence of surface topography on friction and contact parameters, and the influence of friction and contact parameters on friction squeal are reviewed. Moreover, the generation methods of rough surface are introduced to facilitate the research. Finally, on the basis of a discussion on difficulties and shortcomings of the former research, recommendations are proposed for future research.
