| Abstract: | Noise from a vehicle is always a concern for any automotive industry looking for passenger comfort. This also holds for the different types of brake noise, in particular for squeal, which is a source of discomfort both to passengers and passers‐by. Intensive research on low frequency squeal (noise between 1‐5 kHz) has been carried out. A model of the floating caliper disk brake has been recently proposed by the authors with the aim to predict the onset of squeal. A flutter type instability resulting from nonconservative restoring forces is assumed to be the reason behind squeal in this model. The problem of validating the model against experimental observation lies in the fact that all the system parameters included in the model, especially the disk, are to be carefully chosen. In this work some parameters of the disk are estimated and a method is suggested to estimate these parameters in a systematic way. For that purpose, the values are to be accurately selected by experiments and modal updating technique. (© 2004 WILEY‐VCH Verlag GmbH & Co. KGaA, Weinheim) |
