摩擦制动低频振动噪声的研究现状

A Review on Frictional Braking Low-frequency Noise and Vibrations

通过分析总结过去几十年的研究文献,从试验研究和理论研究两方面来详细介绍汽车摩擦制动引起的低频振动噪声的国内外研究现状,其中重点介绍了制动颤振和制动抖动两种低频制动噪声和振动的产生机理、理论建模和实验研究工作。最后,对有效解决摩擦制动产生的低频振动和噪声的技术和方法进行了展望并提出建议。

Based on literature studies of frictional braking noise and vibrations in the last decades, the low-frequency braking vibration and noise is reviewed on both experimental and theoretical development in this area. The focuses are the mechanism, theoretical modeling and experimental study on groan and judder of low-frequency braking noise and vibrations. In the conclusion, prospections of new and efficient methodologies and techniques in the control of frictional braking low-frequency noise and vibrations are presented and discussed.
