Abstract
AbstractBased on consulting a number of literatures, the classification of brake vibrations and noises, a review of mechanisms, research methods and influence factors on break groan which has not been researched in China was presented. The brake groan results from the stick-slip moving between the brake disk and pads. The research methods include test research and theoretical research, and the latter can be divided into the methods of linear and nonlinear system dynamics, multi-body system dynamics and finite element analysis. System friction, mechanical system parameters and power transmission system parameters are the factors that influence brake groan. Finally, it is pointed out that the future research should focus on the mechanism of brake groan as well as the influence parameters in vibration source and transmission path systematically to instruct the matching and optimization of system parameters.
