Abstract

Disc brakes are widely used for regulating the speed of the vehicle by hindering the rotation of a wheel. During each braking cycle, disc brakes are subjected to high thermal loads due to the squeeze action between pad-disc pair. Material selection and design of a brake plays an important role in the dissipation of heat generated. The present work attempts to increase the surface area for maximum heat dissipation of a disc brake by introducing different patterns of holes, slots and groove combinations in the base design which is a plain disc. For analysis purpose, the geometrical parameters such as the outer and inner diameter of plain disc are fixed as 240 mm and 140 mm respectively with reference to the standard dimensions of disc brake used in Honda Unicorn bike. Thermo-structural analysis is carried out on the seven different geometric models of disc brakes with Carbon fiber reinforced silicon carbide material (C/SiC). Steady state temperature variations, transient structural deformations and Von Mises stresses were determined. A rotor with minimum deformation, low stress level in comparison with the existing designs were developed. The results show that the Model-3 with elongated holes at the outer surface has a relatively lower temperature which is about 49.3% lower as compared to base model indicating higher heat dissipation.
