Experimental Analysis of Low-Frequency Brake Squeal Noise

For low frequency brake squeal (1-3kHz) anti-squeal shims are not always effective Development of an appropriate reduction method is therefore an important issue Theoretical analysis of low-frequency squeal has been shown by many papers But presently the squeal reduction method is not sufficient for vehicles

In this study we measured brake component frequency response during brake application with stabilized friction surface condition This method enabled us to find the optimal rotor natural frequency and reduce low-frequency brake squeal
