A brake is a mechanical device which inhibits motion. A drum brake is a brake that uses friction caused by a set of shoes or pads that press against a rotating drum-shaped part called a brake drum. The brake drum is a critical component that experiences high temperatures and develops thermal stresses during application of brakes. In addition, the application of shoe pressure gives rise to mechanical loads. So the analysis takes into account both the thermal stresses and mechanical stresses together. Brakes in cars and trucks are safety parts. Requirements not only in performance but also in comfort, serviceability and working lifetime are high and rising. I.e. the brake pad with the friction material, the counter body and calliper, can be modelled. When the brake is applied an excess amount of heat is produced due to friction. By the presence of heat, the strength of brake may be reduced it is necessary to study the effective heat transfer in the brakes. The main objective of this project is to conduct transient thermal analysis on the brake to find out proper cooling time. And effective material for a drum brake. The cad model is generated in solid works premium 2013. And thermal analysis is done in solid works simulation.
