Abstract

Noise and vibrations associated with the braking process are mainly affected by the coefficient of friction . The aim of this work is to study the effect of principal parameters i.e. normal force, sliding speed and wedge inclination angle on the dynamic linear analysis of wedge disc brake and their comparisons with conventional disc brake system. The coefficient of friction is measured and expressed as a function of sliding speed and normal force for the two types of disc brakes. The results illustrate that there are noticeable differences in wedge disc brake resonance frequency and shoe factor step response with variations of coefficient of friction and wedge inclination angle. However, the coefficient of friction has a slight effect on the dynamic characteristics in the case of conventional disc brake. It was noted that the sliding speed has a considerable effect on wedge disc brake dynamics. It was concluded that the normal force has little effect on disc brake dynamic characteristics for both brakes.
