Modal Coupling Analysis of Brake Discs

抄録

The topic of this paper is to investigate the causes of squeal under the operation of brake systems. We firstly confirm the validity of the finite element model through experimental modal analysis (EMA) for actual a brake disc and linings, and also verify the agreement with value of modal assurance criterion (MAC) between the mode shapes obtained from finite element analysis and EMA. Furthermore, we evaluate the possibility of squeal for various parameters of brake system, and also estimate the frequency and stability of modal coupling to the brake disc under consideration.
