2、r of a wedge disc brake are presented in this article. The friction coefficient has a significant role in the brake system dynamics especially, self-energized. A set of experiments have been conducted to formulate mathematical equations relating the friction coefficient, normal force and sliding spe
3、ed. The effect of main operational parameters of a wedge disc brake such as normal force, sliding speed and wedge angle on the dynamic behavior and their comparisons with conventional disc brake system are investigated. Setting time and frequency response are the main performance indicators to inves
4、tigate the dynamic behavior of a disc brake. The results indicate that friction coefficient significantly influence the resonance frequency and setting time of wedge disc brake shoe factor. However, the coefficient of friction has a negligible effect on setting time or resonance frequency of convent
5、ional disc brake. The effect of sliding speed on a wedge disc brake dynamics is somewhat considerable but it has a little effect on the dynamics of a classical disc brake. Moreover, the wedge angle has a considerable effect on the wedge disc brake dynamics. The normal force has negligible influence
6、on dynamic characteristics of wedge and conventional disc brakes. Keywords: Disc brake dynamic behavior; Friction coefficient; Brake shoe factor; Wedge angle; Self-energized brake 1. Introduction Many researchers are trying to develop the vehicle disc brakes that may ensure better performance under severe service conditions. The expanding necessities identified with high safety, and better ride comfort of modern vehicles makes them turn out to be more perplexing. These high and principally
