Authors Abstract
Content
Regarding the vibrational characteristics of a brake disc causing brake squeal, there are two factors: eigenmode alignment (or natural frequencies) and damping capacity. Focusing on the effects of dimensions on damping capacity of a brake disc, intensive CAE experiments for analyzing the effects were conducted. It was found that disc damping capacity can be increased independently of natural frequency by modifying disc dimensions. It was also found that peak accelerance obtained from a frequency-response function of a brake disc is an effective parameter for evaluating damping capacity of a brake disc.
