Squeal suppression through a tuned fuzzy damper: a numerical study

Despite over a century of research on brake squeal, an effective solutionfor its suppression has not yet been achieved. The scientific community agrees that squeal is caused by a coupling between modes of the rotor with modes of the pads, however, the complexity of commercial brakes representsan obstacle to design an effective solution to this problem. For this reason several researchers focused their study on the beam-on-disk that exhibit a similar instability. This paper proposes an innovative passive damper, based on the theory of pseudo damping, that completely suppress squeal occurrence on the beam-on-disk. (A)
