Abstract

Disc brakes are exposed to large temperature resulting large thermal stress during routine braking. These large temperature extrusions have two possible outcomes: fade that generates reduction in stopping power; and large amount of plastic deformation that generates low fatigue life in the brake rotor. The aim of the present work is to investigate the temperature distribution of Aluminum alloy disc brake during first braking phase using analytical, as well as for mild steel in finite element (FE) method and comparing the result. The area of study is concentrated on temperature variation as a function of time only. Only the areas exposed to high temperature is selected for analysis, specifically the rotor, by excluding hub and vanes because they are for from disc-pad contact. One particular existing brake disc design for a SUV car of model mahindra is chosen for the investigation. The dimensions, material property and maximum allowable speed of this car are used as an input both for analytical and finite element method.. The finite element simulation for the coupled transient thermal field and is carried out by separate data base thermal coupled method based on NX9 to evaluate the temperature profile. The result show maximum temperature and at the surface and these affects tribological properties such as damage and failure at the surface of the disc.
