ABSTRACT
In disc brakes, the relative motion of the disc-pad
surfaces may results in a loss of tool material through
adhesive wear. This wear processes are initiated by
the interfacial adhesive junctions that form in contact
zone. As a normal load is applied, local pressure at
the contact area become extremely high. Therefore,
the surfaces adhere together. The friction between the
sliding surfaces induces the generation of wear
particles. The presence of particles with high hardness
accelerates the wear by abrasion. The rate of wear is
affected by parameters such as pad-disc material,
velocity and temperature.
The aim of this paper is to provide a finite element
model allowing for the numerical simulation of the
wear evolution within the brake disc-pad system
during rotating.Copyright © 2003 IFAC
