The brake drum is a specialized brake that uses the concept of friction to decelerate or to stop the vehicle.
The deceleration is achieved by the assistance of the friction generated by a set of brake shoes or pads.
During the brake operation heat is ejected out this causes damage to the brake. Disc (Rotor) brakes are
exposed to large thermal stresses during routine braking and extraordinary thermal stresses during hard
braking. To satisfy this condition the drum material should possess a high thermal conductivity, thermal
capacity and high strength .The common material used for construction of brake drum is cast iron.
The aim of the project is to design, model a disc. Modeling is done using catia. Structural and Thermal
analysis is to be done on the drum brakes using four materials Stainless Steel, gray Cast iron, carbon carbon
composite & aluminum metal matrix. The shoes of this kind of brake are contained within the drum and
expand outwards when the brake is applied. Such kind of brakes is used in medium heavy-duty vehicles.
Structural analysis is done on the drum brake to validate the strength of the drum brake and thermal
analysis is done to analyze the thermal properties. Comparison can be done for deformation; stresses,
temperature etc. form the three materials to check which material is best. Catia is a 3d modeling software
widely used in the design process. ANSYS is general-purpose finite element analysis (FEA) software
package. Finite Element Analysis is a numerical method of deconstructing a complex system into very small
pieces (of user-designated size) called elements.
