Abstract
The brake system is a basic and one of the most important systems of an automobile vehicle. Brake rotors of disc brakes rotate with the wheels, and brake pads, which are fitted to the brake calipers, clamp on these rotors to stop or decelerate the wheels. They convert the vehicles kinetic energy into heat, vibration, and sound energies, so that the vehicle can be brought to a halt. This change in energy occurs between the brake pads and the rotors or disc in a disc brake system. In this study we focus on the high thermal stresses endured by the disc during this energy conversion. Due to these stresses, the material used for the discs becomes a very important factor as we have to choose the right material which can make these discs efficient and more durable. In this research work, the Formula Student Vehicle disc has been chosen and simulation of the thermal stresses and fatigue analysis with different materials of stainless steels (SS) grades like SS 304, SS 410, SS 321, and SS 310 was carried. These materials were chosen as these are readily available and the cost of manufacturing of these discs will be reduced. By the use of Solidworks software, the disc is designed. With the help of Ansys workbench, the simulation of the thermal stress analysis and fatigue of the discs is done. From this research output, the stainless steels grade SS 410 had better results.
