Abstract

Passenger cars have become one of the main transportations for people travelling from
one place to another. Indeed, vehicle quietness and passenger comfort issues are a major
concern, One of vehicle components that occasionally generate unwanted vibration and
unpleasant noise is the brake system. Brake squeal noise is the most troublesome and
irritant one to both car passenger and the environment, and is expensive to brakes and
carmakers in terms of warranty costs.
Brake squeal has been studied over 20 yeurs ugo through experimental, analytical and
numerical methods in an attempt to understand. to predict and to prevent squeal
occurrence. In recent years, the finite element (FE) method has become the preferred
method due to inadequacy of experimental methods in predicting squeal at early stage in
the design process. However, the drawbacks of the FE method are over-predictions and
missing unstable modes in the squeal frequency range,
This paper attempts to improve the drawbacks by considering temperature effect,
which is typically neglected by many previous investigators. Prediction of disc brake
squeal is performed using complex eigenvalue analysis that available in ABAQUS V6,4, In
doing so, a validated and detailed 3-D finite element model of a real disc brake is used.
Predicted results are then compared to those obtained in the experimental results with and
without the effect of temperature
