The brake drum is a specialized brake that uses the concept of friction to decelerate .The deceleration isachieved by the assistance of the friction generated by a set of brake shoes or pads. During the brake operation heat isejected out this causes damage to the brake. To satisfy this condition the drum material should possess a high thermalconductivity, thermal capacity and high strength .The common material used for construction of brake drum is cast iron.A thermal analysis of different materials such as aluminium alloy, cast iron and stainless steel 304 for a brake drum willbe done. Grey cast iron is the conventional material used for making brake drums of light and heavy motor vehicle. Theproblems encountered in the cast iron material are described. An Al MMC brake drum has been designed to replace theheavy cast iron brake drum of a typical passenger vehicle. The design parameters such as inner radius, outer radius, andthe width of drum, load and the allowable deformation are kept same for both cast iron and MMC brake drum. Themaximum temperature that is generated is calculated with the help of the ambient temperature for all the three materials.The area of cross section is calculated and thus their weight is calculated for three different densities of the threematerials. A model is created with the help of computer aided drafting software, namely CATIA. Steady state condition isstudied for all the three materials. Then thermal deformation is calculated assuming a pressure of one Newton is appliedas a braking energy or force. A comparison of all the three results is done and MMC material is proved better than theother materials.
