Study the noises phenomenon in the brake system

Abstract

The noise and vibration generated by the braking system in passenger cars are important technical and economic problems in the automotive industry.

In recent years, the finite element (FE) method has been found to be a useful tool in predicting the occurrence of noise in a particular brake system during the design stage.

This paper presents a more refined FE model of the disc brake corner that contains the wheel hub and steering knuckle. The model is an extension of earlier FE disc brake models. Experimental has been modelled analysis of the disc brake system is initially used to validate the FE model. The unstable frequencies were then predicted by applying a complex eigenvalue analysis to the FE model. Finally, a number of structural modifications are made and simulated to evaluate brake squeal at the design stage.

Overall Aim The over all of aim of this paper is to study the noises phenomenon in the brake system and developed method to minimize this noise though the experiments and simulation to help designers and industries to understand the effect of vibration on disc brake rotor, and also to understand advanced data analysis methods by using ABAQUSE software.
