Abstract
This paper presents numerical studies of friction-induced instabilities of brake systems using complex mode analysis. The complex eigenvalue extraction is performed at a deformed configuration; thus, nonlinear effects are taken into account in the modal analysis. An example case is used to illustrate the importance of friction-induced damping and nonlinear effects in brake squeal analysis. It is found that the inclusions of lining wear, geometric nonlinearities, and positive as well as negative frictional damping effects have significant influence on the brake squeal predictions.
