A disc brake is a type of brake that uses calipers to squeeze pairs of pads against a disc or rotor to create friction. This action retards the rotation of a shaft, such as a vehicle axle, either to reduce its rotational speed or to hold it stationary. The energy of motion is converted into waste heat which must be dispersed.
Hydraulically actuated disc brakes are the most commonly used form of brake for motor vehicles, but the principles of a disc brake are applicable to almost any rotating shaft.
The subject of friction and heat transfer effect on brake performance and brake disc’s life. One of the most important components of every vehicle is its braking system. It is necessary that the brake system works without fail, and designers are always looking to improve its performance. The friction brake system is one of the common types of brake systems in which the kinetic energy of the vehicle is converted into thermal energy by the friction between the disk and the brake system components. If the temperature’s rise is high, the friction will be reduced and the brakes do not work well. Therefore, an increase in the heat transfer speed from the braking system to the surrounding environment is desired by the designers.
In this analysis, the heat transfer on the brake disc surface is simulated and analyzed by Ansys Fluent software.
