Analysis of disc brake with composite materials

Abstract

While braking, frictional heat raise temperatures at the disc/pad interface. Due to which rotor's surface may experience early wear, thermally elastic instability, brake fluid vaporization, and thermally stimulated vibrations as a result of an excessive temperature increase brought on by frictional heat. In order to increase braking effectiveness and improve vehicle stability, an investigation on the use of various materials for the disc brake rotors of two different vehicle types, one of which is solid and the other of which is vented is carried out. The disc brake is modelled using modelling software CATIA and Finite element analysis (FEA) is carried out using ANSYS 14.5, the toolis able to analyse the temperature distribution, stress variation, and deformation over the rotor's profile of the disc brake rotor. After considering the impacts of temperature distribution, Vonmises stresses, and deformation. In this work analysis of disc brake is done with three materials (Aluminium Metal matrix composite, Mild steel and cast iron) used for vented with and without holes type disc brakes. Conferring to the results, Aluminium MMC is observed to be the optimum material for disc brakes where the deformation is minimum at mode shape 3 at frequency 597.1 Hz when compared to other mode shapes.
