Abstract
Brake squeal noise which is caused by friction-induced vibrations has been considered as one of the most difficult problems in the automobile industry. In recent years, finite element (FE) simulations are widely used for simulating disc brake squeal and the main objective of this research is to provide new insights into the squeal generation the importance of the friction coefficient using the FE model. A detailed 3D-FE model of a commercial disc brake assembly is created in order to predict squeal behavior. The FE model is validated using the results of the components and assembly's experimental measurements, followed by using a complex eigenvalue analysis to assess the braking stability. It is found that the validated FE model by experimental modal testing of the brake components and assembly can predict the disc brake squeal with satisfactory accuracy. It is also found that the probability of squeal noise Propensity increases with increasing the coefficient of friction between the disc and the brake pads.
