Abstract
During the braking process of a car, the temperature of the brake system increases continuously, and if the cooling performance of the brake system is insufficient, accidents can occur. For this reason, in this study, the experimental method of the Taguchi design was used to optimize the design of a ventilated brake disc with radial vanes using three design parameters (i.e., number of vanes, vane thickness, and steering angle), and the airflow and temperature distribution around the brake disc and tire were simulated using finite elements. The simulation results show that the solution in this study can increase the ventilation gap from 10 to 14 mm, the bending angle of the blades from 29° to 37°, and the cooling effect after emergency braking by 6.1% and 8.8%, respectively, when dissipating heat for 100 s at a driving speed of 60 km/h.
