Content
This paper provides a systematic approach to identify the root cause of the squeal noise of a disc brake by using advanced experimental tools. Modal analysis was used to identify the modal participation factors when the brake was squealing according to the reproduced squeal phenomenon and acquired operational displacement shape (ODS) using pulsed electronic speckle pattern interferometry. Modal coupling between the disc and pad/caliper assembly is found to be the key to produce squeal. It has been demonstrated that using mass loading/damping can de-couple the modes between the disc and pad/caliper assembly and reduce the assembly vibration from which the squeal is eliminated.
