Abstract

Carbon ceramic brake discs have better performance over the conventional steel brake discs commonly used in high-speed trains. This study analyses the heat dissipation characteristics and their influence on carbon ceramic brake discs. Through FLUENT numerical simulation, the surface temperature of the brake disc and the temperature distribution at different positions of the semi-enclosed space under the vehicle are obtained. The temperature rise of the carbon ceramic disc and the heat distribution law of the carbon-ceramic braking friction pair near the space area under the complex structure of the vehicle are revealed, and the influence of the heat dissipation of the brake disc on the service characteristics and structural safety of the surrounding parts is analysed.
