ABSTRACT:
The vibration damping properties of brake rotors and drums can be represented accurately and repeatably by a single factor obtained from a curve fitting based on an eighth order sine function. A series of test points is used to measure resonant frequencies and vibration decay times around the periphery of a part. This data is then used to determine Q-factors which are found to vary sinusoidally around an annular brake part.
