THERMAL ANALYSIS OF BRAKE DISC

Abstract: In today’s developing automobile sector, there is drastic change in the technology from transmission system to braking system. The braking system is considered as one of the most important system from performance as well as safety point of view. When the brakes are applied to the moving vehicle, all the kinetic energy of the vehicle get converted into equivalent amount of heat generation. Disc brake is the recent trend in automobile vehicles which dissipates the heat faster than the conventional drum brakes. but if hard braking is done, there is induction of thermal stresses in the brake disc which leads to generation of excessive temperature .if this heat is not dissipated properly, then distortion will be get produced in the disc which leads to thermal cracking of the disc leading to disc failure. The brake disc has an inherent ability that there is no change of co-efficient of friction on the disc so there is no problem of brake fading phenomenon. The main advantage of disc brake is that only a small portion of the disc is in contact with the friction material i.e. the caliper. Hence there is large surface area of the disc which can dissipate the heat to the atmosphere. Specifically the heat dissipated to the atmosphere is the forced convection mode. The aim of this research work is to choose best profile and best material which can dissipate maximum amount of heat to the surrounding. The models of disc are created in Creo parametric 2.0while the analysis is conducted in ANSYS 15.0.the analysis performed in ANSYS is steady state thermal.
