Item EVALUATION OF THE THERMAL PERFORMANCE OF AUTOMOTIVE BRAKE DISC(2023-01-27) ERKILIÇ, Kaan Tamer; JAFARI, RahimAcceleration is a crucial dynamic for a vehicle, although deceleration is the key element for vehicle safety. A vehicle's braking system is the sole piece of equipment that can bring it to a slowdown or halt. The function of a brake system is performed with the friction between disc and the pad. The thermal performance of the components it contains must be measured precisely in the design and test steps, and the component must show the required performance under operating conditions. In this study, an experimental setup was designed and produced to observe both aerodynamic and thermal characteristics of brake discs. Parts such as disc, pad, rim and tire on the experimental setup are exactly the same as those used in a typical passenger car. The quarter weight of a passenger car was adapted to the experimental setup on the shaft with cylindrical weights. In addition, a repetitive braking scenario was used in the experimental setup and simulations of the aerodynamic and thermal outputs of braking were carried out using detailed numerical models. In the experiments and simulations, it was observed that the air flow caused by the acceleration of the vehicle reduced significantly inside the rim, despites there was a turbulent air flow that takes place with the form of eddies inside the rim. As a result of thermal simulations and experiments, the temperature distribution on the brake disc has been observed, and it has been predicted that the area where the brake disc contact with the brake pad is higher than the temperature of the area directly opposite the contact area and the temperature is not uniformly distributed across the brake disc.
