Abstract

The numerical analysis method for predicting the disk squeal simply and accurately has been studied by using the Substructure Synthesis Method. First, some experiments are carried out in order to understand the brake squeal phenomenon. Second, the numerical analysis method based on the Substructure Synthesis Method is conducted. Finally, the analytical results are compared with the experimental ones. As a result, it is found that the brake squeal occurrs when the natural frequency dominated by the disk coincided with that dominated by the caliper with the increase of the friction coefficient, and the analytical method developed here is found to be useful for prediction of the brake squeal.
