Many analytical approaches have been proposed in the literatures to evaluate the brake squeal dynamics, the complex eigenvalue approach probably being the most popular. Although this method is generally accepted, it suffers from several drawbacks. One is that the analysis does not provide a clear indication of the squeal mechanism. Another is that the predictions are sensitive to slight changes to the system model. For this reason, a variation of the complex eigenvalue approach has been developed that is more robust and provides insight into the squeal mechanism. In this paper, the new method is used to identify the types of modal coupling mechanisms that lead to squeal. Based on this investigation, the authors present three different types of mode coupling conditions that cause squeal.
