Influence of Pad Geometry on the Thermomechanical Study of a Disc Brake
Abstract
The fundamental objective of this work is to studythe thermomechanical behaviour of a disc brake with variousgeometric pad configurations, maintaining the same contactsurfaces and by varying the magnitudes of the inner contactradius r_{int} and contact angle θ , through the braking processusing dry contact sliding conditions. A feedforward analysis iscarried out to find the maximum temperature, the global strains,the Von Mises stress on the disc and the contact pressures on thepads at various times of the simulation. In the thermomechanicalmodelling of disc braking, the disc/pad wear depth distributionwas determined on the basis of Archard’s law, considering thecontact pressure, specific wear rate and sliding velocity.
