A Study on the Stability of the Low Frequency Vibration Non-Linear 2-DOF Model of Drum Brake

On the basis of a 2-DOF non-linear drum brake vibration model at low frequency, the present paper discusses the effect of the structure parameter on the stability. The result shows that, even when the friction coefficient is constant, the vibration and instability can occur with the combination of some specific parameters. Hence the paper indicates the principle of the vibration of the drum brake at low frequency from another point of view. Keywords-component; Drum-brake; Non-linear; Vibration; Stability
