Abstract
This study aims to analysis the thermo-mechanical behavior at dry contact between disc and pad during braking phase by computer simulation. The geometric design model of disc analyzed at transient temperature to embody the ventilation system in vehicle. Deformation, Von Mises stress and contact pressures at pad are investigated by coupled thermo-mechanical. These simulation results are satisfactorily verified by comparing with similar literature result. Thus, this study provides effective reference for design and engineering application of brake disc and brake pad.
