Disc brakes are usually subjected to extreme stress during heavy braking. It converts kinetic energy to thermal energy by producing an opposing braking torque, and the generated heat energy is exhausted into the atmosphere. The most common problem with disc brakes is that natural air circulation is insufficient to cool down the heated brakes. Different types of ventilation systems are used to overcome this problem, and if not used, then it may lead to crack formation. In the case of cars, an extruded assembly known as vanes is used for ventilation, and air acts as a cooling agent when it flows through the vanes. This leads to a decrease in temperature and thermal stresses generated by continuous braking in different traffic conditions. This study mainly focuses on Kangaroo Paw Ventilation and its comparison with straight radial vanes. A thermo-mechanical analysis of an automotive disc brake is performed, and transient thermal and static structural analyses are used to get results of temperature distribution, equivalent stress, equivalent strain, and total deformation. The 3D model of a brake is created on Autodesk Fusion 360, and further, this model is analyzed on ANSYS 15 Workbench. This thermo-mechanical analysis is performed using two different materials: Aluminum Alloy 6262-T9 and Grey Cast Iron. In the case of straight radial vanes, a parametric study is also performed by changing the number of vanes. The results obtained after analyzing the disc brake indicate that Kangaroo Paw ventilation performs better than straight radial vanes.
