Analysis of Disc Brake Rotor Coning

Abstract

Disc brakes operate on the principle of friction by converting kinetic energy into heat energy. The main objective of a disc brake rotor is to store this heat energy and dissipate it as soon as possible. During the repeated braking the heat generated accumulates within the rotor and the heat transfers through convection on both the sides of the rotor are not uniform due to the wheel rim covering so heat accumulates on the wheel covered side, during next instance of braking the surface acts like an plastic material due to accumulated heat and it deforms due to the force acting in it and this deformation fails to make surface contact with the pad instead it makes line contact which further paves way to temperature increase and hence lead to break failure. My work in this project to do thermal analysis and structural analysis and couple them by suitable method and find the deformation gradient for various temperatures generated during braking process. Based on the deflection results produced various combination of material for improving the heat dissipation is analyzed by adopting the procedure followed for better comparison of data
