Abstract:
An analytical model based on finite element method and a modal coupling approach used for evaluating high frequency disc brake squeal is discussed. The model incorporates the pad-rotor mode locking effect, which is responsible for a good share of high frequency disc brake squeal problems. The application of the model in the optimization of pad shapes for several vehicle platforms are presented with good correlation to vehicle and dynamometer tests.
