TITLE: THE DESIGN AND THERMAL ANALYSIS OF A HIGH-SPEED TRAIN BRAKE DISC
AUTHOR(S): F. Karacam, Y. Cakar
ABSTRACT: Brake discs used in high-speed trains are one of the most critical components of these systems. They convert a significant amount of kinetic energy into heat through friction. The high temperatures generated during the process cause thermal stresses, microstructural changes, and surface wear in the disc material, directly affecting its performance and lifespan. Therefore, investigating the tribological and thermomechanical behavior of brake discs is crucial in the optimization of safety, durability, and maintenance costs. In this study, the thermomechanical behavior of brake discs used in high-speed trains will be investigated by use of a computer-aided engineering approach. After modeling the brake disc that satisfies the specific operating conditions, thermal analysis will be performed to obtain values for temperature and heat flux. The variation of these parameters will be presented graphically, and the performance of the brake disc will be analyzed.
