Description

This paper deals with the analytical recurrence of the squeal and chatter phenomena generated in a certain type of bicycle disc brake unit. The squeal is in-plane vibration in the direction of a disc surface with frequency about 1000Hz caused by frictional characteristics with negative slope with respect to the relative velocity. The chatter is generated within a certain limited region of high temperature, and is another frictional vibration in which the squeal and the out-of-plane vibration of the rotor due to Coulomb friction are added together through the internal resonance relation between in-plane and out-of-plane nonlinear vibrations caused by the temperature increase of the rotor during braking. This paper regenerates these two nonlinear vibration phenomena with a linear numerical analysis of the both in-plane and out-of-plane vibrations. The simple analytical model includes spokes, disc, hub and caliper which are important components to generate the vibration phenomena.
