A method for determining the geometric stability characteristics of a brake comer module(BCM) is presented. Since disc brake squeal noise typically occurs at unstable resonant frequencies of a system, the likelihood of disc brake squeal for a particular design can be determined. Finite element methods are used to derive complex eigenvalue about a brake comer module. Some unstable modes calculated by finite element methods correspond to squeal noise data. Through kinetic energy participation analysis for each parts of BCM, we can efficiently predict about squeal noise data.
