Literature Survey of Friction Induced Automotive Brake Groan

Abstract:

Frictional brake groan is selfexcited lowfrequency structural vibration and associated airborne noise, which has obvious intermittent and impulsive characterizations. Hence, a comprehensive literature survey on brake groan is conducted from the aspects of experimental studies, generation mechanisms and related theories, modeling and simulation analysis. These researchs'results suggest that in order to study the mechanism of brake groan and restrain it, the focus of the following researches should be taking the multidimension in space motion of the brake system and suspension system into consideration.
