摘　　要：为了减少汽车制动抖动的售后抱怨,降低索赔成本,提升用户满意度,文章对制动抖动问题的国内外研究成果进行了归纳和总结。首先对制动抖动问题的特征及类型进行了阐述,然后分析了产生机理及影响因素,最后有针对性的提出了控制措施。结果表明,制动抖动的直接原因为制动力矩波动和传递路径的放大作用,制动力矩波动的根本原因为制动盘周向厚度差及制动盘端面跳动。最终明确了制动抖动问题的控制措施为控制振源和降低传递路径的放大作用。文章的研究结果可以为解决汽车制动抖动问题的售后分析人员提供参考,也可以为制动系统的前期开发人员提供经验借鉴。In order to reduce after-sales complaints about automotive brake judder,reduce claim costs,and improve user satisfaction,this article summarizes the research results on brake judder issues both domestically and internationally.Firstly,the characteristics and types of brake judder problems are explained,followed by an analysis of their mechanisms and influencing factors.Finally,targeted control measures are proposed.It has been confirmed that the direct cause of brake judder is brake torque fluctuation and the amplification effect of transfer path.The root cause of brake torque fluctuation is disk thickness variation and sideface run-out of brake disc.The control measures for brake judder problem have been clarified to control the vibration source and reduce the amplification effect of the transfer path.The research results of the article can provide reference for after-sales analysts who solve the problem of automotive brake judder,and can also provide experience and reference for early developers of brake systems.
