摘要
盘式制动器的制动尖叫是汽车工业界备受关注的质量问题,也是学术研究领域的一个热点和难点课题。研究盘式制动器尖叫的产生机理,在制动器设计开发阶段进行尖叫预估,并提出抑制措施,对于降低噪音污染、满足顾客要求、加快制动器的产品开发进度,乃至提高汽车产品竞争力,都具有十分重要的意义。从制动尖叫的产生机理、数值分析方法、试验研究方法、影响因素以及尖叫抑制新技术等方面对盘式制动器尖叫的近期研究进展进行综述,众多的研究表明盘式制动器尖叫存在复杂的产生机理,并受到多种因素的影响,利用复特征值和瞬态动力学方法,结合实车道路试验和台架试验,是研究制动尖叫机理、开发低尖叫倾向产品的重要途径。最后总结现有研究存在的问题并对进一步的研究作出展望。
Disc brake squeal is one of the most difficult quality issues concerned by automotive manufacturers and researchers.It is of critical importance to study squeal generation mechanism,predict brake squeal performance and propose suppressing measures in product development phase for decreasing noise pollution,satisfying customers＇ requirements,accelerating new product development to improve automobile competitiveness.The recent research advances were reviewed in the aspects of squeal generation mechanisms,analysis methods,influence factors and new technologies.Latest developments showed that disc brake squeal is caused with complicated mechanisms and influenced with 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 brake vibration characteristics and develop disc brakes with lower squeal propensity.The existing problems and the further study needed in the future were finally discussed.
