Summary:

In this paper, we investigate a method to calculate the dynamic instability of a disc brake system and propose a criterion of design modification. To estimate dynamic instability, complex eigenvalue analysis is performed for a brake system and the contribution factor of each component to an unstable complex mode is calculated using complex MAC(Modal Assurance Criteria). From the contribution factors, the most influential component is determined so as to decouple the complex mode, and its geometry is modified in view of the strain energy distribution. Evaluation through noise dynamometer tests verifies the reduction of squeal noises, and this is in accordance with the results of complex eigenvalue analysis
