Stick-slip oscillations induced by dry friction in an automotive disc brake system
In this paper, we establish a dynamical model of four degree-of-freedom for an automotive disc brake system. We study stick-slip oscillations in both circumferential direction and radial direction of the brake rotor. The stick-slip phenomena are investigated and a complex process has been observed that the system changes from the periodical motion with no stick phenomena to the periodical or chaotic motion with one or more stick phenomena. By numerical simulation, some periodical portraits and chaotic portraits are obtained. The numerical results show that the rotors angle velocity and the nature frequency of the rotor have much effect on the motion of the system. The results also indicate that the pad and the rotor keep stick in radial direction most of the time, but have relative motion between times.
