Proceedings of the Institution of Mechanical Engineers, Part F: Journal of Rail and Rapid Transit, Ahead of Print.
This study aims to investigate the thermal environment of Carbon-Ceramic (C/C–SiC) brake discs during high-speed emergency braking and assess its impact on surrounding bogie components. A coupled fluid–solid–thermal simulation model, together with full-...
