“…MOGA derives each optimal value by considering multiple weights. 25 Table 5 shows the resulting values derived through the HMA algorithm. Since HMA cannot consider weights, a total of 10 weights were directly substituted to carry out the optimization:stress:temperature = 0.1:0.9-0.9:0.1.…”

In this study, the thermodynamic performance of a ventilated brake disc was improved by securing structural stability and verified through bench experiments. A brake disc is a braking device that decelerates a vehicle or stops it, and the disc should maintain a reliable braking force. The temperature rise on the disc surface has the greatest effect on the braking force. In recent years, many studies have been conducted on the shape of the disc in order to secure stable braking force and heat dissipation at the same time. However, as the disc surface is processed further, it becomes more difficult to have stable braking force, although the heat dissipation property is improved. Therefore, in this study, disc shapes were designed to improve heat dissipation performance while maintaining structural performance. The stress and temperature distribution were analyzed using ANSYS and optimal design of disc shapes was performed through PIAnO. In addition, to compare and verify the initial model and the optimized model, a prototype was fabricated to judge the feasibility of the optimization using a dynamometer. It can be expected that the heat dissipation performance and driving safety can be improved by using new brake discs.
