INVESTIGATION OF NOISE AND VIBRATION CHARACTERISTICS OF AUTOMOTIVE DISC BRAKES IN THE LOW FREQUENCY DOMAIN
Keywords:
brake noise, brake vibration, brake dynamometer, scaling method, experimental modal analysisAbstract
Noise and vibration characterisation is an important benchmark to reduce brake noise. Commonly brake noise and vibration measurement is done on an actual vehicle or on a brake dynamometer. Full scale brake dynamometer takes into account the attached mass which resembles the mass of the quarter vehicle. This paper proposes a testing method which eliminates the need for attached masses. This is achieved through the scaling of the brake system parameters to accommodate the loss of mass and produce similar conditions as in actual braking. The measurement of noise and vibration is measured simultaneously and a FFT is performed to identify the frequencies of noise and vibration. An experimental modal analysis (EMA) is done to obtain the frequencies which the brake system tends to produce as a validation to the proposed method. It is shown that through this method the noise and vibration characteristics of the brake system and the unstable frequencies could be identified.References
