DESIGN AND STRUCTURAL ANALYSIS OF DISC BRAKE IN AUTOMOBILES

This paper presents optimized design of performance of disc brake using finite element analysis is to evaluate the performance under severe braking conditions. Cast iron and stainlesssteel are used as disc brake materials. ANSYS 12.0 is a dedicated Finite element package used for determining the temperature distribution, variation of stresses and deformation across the disc brake. It has been made to investigate the effect of the temperature distribution with the deformed shape and stress distribution of disc brake rotor design by usingdifferent braking conditions. From the results of the above data, the service life and long term stability is ensured. A steadystatic structureanalysis has been carried out to investigate the temperature variation across the disc using the axis symmetric finite elements. Further structural analysis is also carried out by Coupled Field Analysis. An attempt is also made to suggest a best combustion of material, flangewidth and wallthickness used for disc brake rotor, which yields a low temperature variation across the rotor, less deformation and minimum Von-misses stress possible.
