The influence of surface topography on friction squeal-A review

Abstract

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.

Effectiveness of synthetic coolant at 0°C on machining of SS304 with PVD coated TiCN tool to evaluate and compare tool wear and surface finish with conventional machining method

“…The surface roughness results are physically validated by means of two-dimensional surface topography carried with SEM [52]. Here the inserts (all four different cases) after carrying out machining with a cutting speed of 250 m/min, for a length of 1000 m with the same input cutting parameters as feed as 0.25 mm/rev, depth of cut as 0.5 are observed under SEM.…”

A numerical study on the impact of lubricant rheology and surface topography on heavily loaded non-conformal contacts

“…Although, several numerical and experimental studies have been carried out on the behavior of traction coefficient in mixed lubrication regime [10][11][12][13][14][15][16][17][18][19][20]. However, the complete mixed lubrication analysis remains to unfold due to the multi-scale nature of rough surfaces [21][22][23]. Previous studies on EHL analysis of non-conformal contacts suggests that EHD traction mainly governs by molecular structure and lubricant rheology [24].…”
