Summary:

AbstractThe dynamics and, in particular, the NVH phenomena in brakes are still in the focus of research. Recent investigations of for example Rhee and others show two principal vibrational forms of the linings on the rotor [1]. The first form is characterized by vibrations where both linings are in-phase (minimal differential torque between the inner pad and the outer pad). This produces in-plane vibrations of the rotor and results in high-frequency squealing events in the brake. The second form is an antiphase vibration of the brake linings with respect to each other (increased differential torque between the inner pad and the outer pad). This produce directly out-of-plane vibrational modes of the disc, which results in lower-frequency caliper and rotor oscillations.One hypothesis is that different wear densities of the linings essentially characterize the two vibrational modes. The wear behavior is not taken into consideration of this paper as it will be discussed in further publications. This paper deals with a low dimensional dynamical system and examines the vibrations, and analyzes essential influencing parameters on the different vibrational events
