Brake Squeal Generation 1999-01-1735

Brake squeal, which is a noise, occurs in the range of frequencies 1 to 16 kHz is an important task for research to develop the vehicle passenger comfort. This phenomena has been studied many years theoretically and experimentally to gain better performance of brake and eliminating the squeal problem. The work presented here is focusing on the effect of the brake pad manufacturing on the generation of brake squeal. A simple proposed three-degree of freedom model has been used in the study to simulate the brake components (pad, caliper, and disc). The brake squeal and frequency response of brake pad has been measured at different working conditions (pressure, sliding speed, and brake pad type). A comparison between the theoretical and experimental work has been made and a good agreement was found between the theoretical prediction of the brake assembly natural frequency and the experimental measurement. Also the results show that the brake squeal components is responsible for brake squeal where the squeal occurs at the natural frequencies for brake assembly components.
