Abstract

Abstract: Disc brake squeal is one of the most difficult quality issues concerned by automotive manufacturers and researchers. It is of critical importance to study the squeal generation mechanism, predict the brake squeal performance and propose the count measures in the product development phase for decreasing the noise pollution, satisfying customer requirements, accelerating new product development to improve the automobile competitiveness. The recent research advances are reviewed from the aspects of squeal generation mechanisms, analysis methods, influence factors and new technologies. Latest developments show that disc brake squeal is caused by complicated mechanisms and influenced by many factors. Utilizing modern design methods of complex eigenvalue analysis and transient dynamics analysis combined with on-road and bench tests is an important way to analyze the brake vibration characteristics and develop disc brakes with low squeal propensity. The existing problems and the further research needed to be carried out in the future are finally discussed.

Key words
