AbstractThe improvements which need in railway vehicles made neccessary also brake systems developing. The main factors affecting the performance and functioning of the brake system are brake force, mass and speed of the train, stopping distance and road curvature. With the operating speed exceeding 120 km/h, very different braking systems and equipment have been developed. In this work, the brake systems such as air brakes, dynamic brakes, parking brakes, vacuum brakes, electro-pneumatic brakes have been considered. Especially, evaluations have been made on brake disc-pad systems, which represent the most important components in terms of safe navigation for high-speed trains operating at speeds of 200 km/h and above. For this purpose, experimental and numerical analysis studies on braking system interactions based on brake disk-pad geometry and material properties were investigated. As a result of this study, important information will be gained on the basis of the detailed analysis of the scientific and applied researches which will contribute to the productivity to the institutions and organizations that are in the design and manufacturing activities on the braking systems of our country railway vehicles.
