A thermomechanical model for the analysis of disc brake using the finite element method in frictional contact

Abstract

In this work, numerical simulations of the transient thermal and the static structural analysis were performed here sequentially, with the coupled thermo-structural method. Numerical procedure of calculation relies on important steps such that the CFD thermal analysis has been well illustrated in 3D, showing the effects of heat distribution over the brake disc. Three different brake disc materials were selected in this simulation and a comparative analysis of the results was conducted in order to derive the one with the best thermal behavior. Finally, the resolution of the coupled thermomechanical model allows us to visualize other important results of this research such as; the deformations, and the equivalent Von Mises stress of the disc, as well as the contact pressure of the brake pads. Following our analysis and the results we draw from it, we derive several conclusions. The choice allowed us to deliver the best suitable of the brake rotor to ensure and guarantee the good braking performance of vehicles.
