Thermomechanical behaviour of dry contacts in disc brake rotor with a grey cast iron composition

Abstract

The main purpose of this study is to analysis the thermomechanical behavior of the dry contact between the brake disc and pads during the braking phase. The simulation strategy is based on the computer code ANSYS11. The modeling of transient temperature field in the disk brake is actually used to identify the factor of geometric design of the disk to install the ventilation system in vehicles. The thermal-structural analysis is then used to couple the deformation established, the von Mises stresses in the disk, and the contact pressure distribution in pads. The results are satisfactory compared to those found in the literature.
