Abstract
During the braking of the automobile, the brake squeal is a direct concern for the driver. Sometimes, the automaker loses revenue from the customer's warranty claims. The automaker needs to solve or alleviate the squealing noise during the brake action. The study aimed to compare the disc brake squeal of general and drilled brake discs. The disc brake squeal is an instability of the disc brake system. One popular theory used in the analysis is Complex Eigenvalue Analysis and simulation using Finite Element Technique. In this work, three models of brake discs were compared: an ordinary brake disc and two drilled brake discs. For drilled brake discs, the first and second models had 30 and 60 holes on the disc, respectively. The study revealed that a more stiffness structure generates higher frequencies than a flexible structure. Each model generated a different amount of unstable frequency modes.
