A Review on the Mechanism and Control Measures of Automotive Brake Judder
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.
