This paper deals with thermal analysis through finite element analysis of rotor disc of disc brake of BAJA SAE 2013
Car. Generally brake systems are designed to apply artificial frictional resistance to the rotating member in order to stop
the rotational motion of a vehicle. The rotor discs are commonly manufactured of grey cast iron[1]. The SAE also
recommend grey cast iron for various applications[2]. So cast iron is being selected for analysis. The objective of
thermal analysis of rotor disc is to study the temperature distribution & related thermal quantities such as thermal fluxes
& thermal gradients & to evaluate the performance under severe conditions. In this present work, an attempt has been
made to suggest best combination of parameters of rotor disc like Material composition, Flange Width & Wall
Thickness. PRO/E wildfire 4.0 & ANSYS 13.0 software is being used for modelling & analysis of rotor disc. The
Dimensions of an existing Maruti 800 car’s disc rotor of disc brake are taken[3]
