Abstract
The objective of this study is to compare the different thermal characteristics of a material, and how they vary when used in an automobile’s disc brake. It is vital that a brake rotor is able to efficiently dissipate heat for its proper functioning. Overheating can lead to warping of the rotor and even stress cracks in some situations. Furthermore, ineffective dissipation of heat can also lead to brake fading which has been the root cause of accidents time and time again. Being a wear and tear product, they are meant to be periodically replaced. But, optimising the design keeping heat dissipation in mind will prolong the intervals between replacement, and prevent premature failure. By simulating the functioning of the brakes under different conditions, the maximum withstand temperature, pressure and heat can be find out before distorting. Using this information, the material is selected that can endure the specific level of heat and friction while maintaining efficiency over time. Doing this will help reduce the dependence on driving characteristics to get the most out of your brake rotors. Upon studying the simulation results of the disc brakes made of the three selected materials - Stainless steel 420, Grey Cast Iron and Aluminium 7068, Stainless steel 420 showed the best heat dissipation rate and mechanical strength under the selected test conditions.
