Abstract

A variety of components and systems in a vehicle are involved in brake judder. Up to the present, many papers have explored the roles of the brake and suspension in judder, but quite few have taken up the analysis of the vibration behavior of transfer systems, such as the steering system, subframe and body, from a viewpoint of their impact to brake judder.This study employed bench tests to reproduce driving conditions. In order to analyze the transfer system, vibration of the entire vehicle was measured and behavior analysis was performed by visualization of vibration phenomena. Much was learned about the vibration behavior of the steering system, subframe and body, and the basic mechanism of brake judder involving the entire vehicle was proposed.In addition, the influential factors in the transfer system were identified, and the contribution of each was analyzed.
