Structural Analysis of Rotor Disc of Disc Brake of BAJA SAE 2013 Car through Finite Element Analysis

This paper deals with the structural analysis of rotor disc of disc brake of BAJA SAE 2013 CAR through finite element analysis approach using ANSYS software. A disc brake is a device by means of which artificial frictional resistance is applied to the rotating member, in order to stop the motion of a machine or a vehicle. The rotor discs are commonly manufactured of grey cast iron. The SAE also recommend grey cast iron for various applications. So it is being selected for investigation. The objective of structural analysis of rotor disc is to study & evaluate the performance under severe conditions & to suggest best combination of parameters of rotor disc like Flange Width, Wall Thickness & Material composition. In this present work, an attempt has been made to investigate the effect of stiffness & strength and to analyse the stability & rigidity of the rotor disc. The modelling of rotor disc is done in PRO/E wildfire 4.0 software. Further Structural analysis is done by using ANSYS 13.0 software. The Dimensions of an existing Maruti 800 car’s disc rotor of disc brake are taken.
