A Study for Failure Examples of Brake Judder with Abnormal Vibration of Disc Brake

Abstract

Brake judder is one of the most serous problems in automotive-brake systems.it has not been eradicated despite all the efforts that many researchers and engineers have made the reduce it by studying its causes and mechanisms. Brake discs play a significant role in judder.The driver experiences judder as vibrations in the steering wheel,brake pedal and floor.in the higher freqency range.the structural vibrations are accompanied by a sound. Brake judder primarily affects the comfort but could,when confronting an inexperienced driver for the first time,lead to faulty reactions and reduced driving safety.

Stick–Slip Characteristic Analysis of High-Speed Train Brake Systems: A Disc–Block Friction System with Different Friction Radii

“…Braking is realized by disc-block friction to consume the kinetic energy of the train. However, this friction mode may cause unstable vibration [1][2][3][4][5], which disables the brake calipers [6,7], damages the brake disc structure [8][9][10], and reduces the service life of the brake pad [11][12][13]. It will even lead to abnormal noise [14][15][16], which significantly affects the comfort of passengers and residents near the railway line.…”
