Geometric Tuning of Insulators for Brake Squeal Attenuation

This paper explores the use of geometry of the insulators in attenuating brake squeal. The authors present both simulation and experimental data at component level as well as system level - comparison of brake dynamometer test results of a brake system with and without the geometric tuning of the insulators. Also the authors show the effective usage of the geometry changes to tackle squeal frequencies that are outside of brake pad modal spectrum.
