制动摩擦噪声产生机理与控制方法的研究进展

制动摩擦噪声对乘坐的舒适性、城市环境有重要影响。深入研究制动器摩擦噪声的产生机理对于控制其振动与噪声非常重要。评述了近30年来制动摩擦噪声产生机理与控制措施的研究进展,将制动摩擦噪声的产生机理归为自激振动、结构不稳定和"热点"理论三类,并从优化制动器结构、改善摩擦副材料特性等方面分析了制动摩擦噪声的控制措施。为了更好地认识制动摩擦噪声的产生机理和探讨其控制措施,建议从摩擦学、动力学与传热学多学科交叉的角度研究和分析摩擦噪声。

Research Advances of Mechanisms and Control Methods of Friction-induced Braking Noise

The friction-induced brake noise has important influence on the riding comfortableness and urban environment. The investigations on the mechanisms of friction-induced brake noise are significance to determine the control measures. The literature survey on the progress of the mechanisms and control measures of friction-induced brake noise during the past thirty years is briefed. The mechanisms of the noise are divided into three classes; they are self-excited vibration, structure instability, and “hot spot” theory. The control measures are analyzed from the structural design optimization and modify the material performance. In order to acquire better understanding of the formation mechanism and the control methods of friction-induced noise, the further study on friction-induced brake noise should be carried out by combining the inter-disciplines including tribology, dynamics and heat transfer.
