摘要
•In this paper, the research status of rail vehicle brake disc is summarized from five aspects: mode, vibration, temperature field, stress field, wear and fatigue crack. It is found that most of the research focuses on internal excitation such as brake disc material, structure and its own braking condition, and the brake disc is jointly affected by internal and external excitation in the braking process. Therefore, the research can be carried out from the aspects of wheel-rail excitation, heat transfer between brake disc and axle.
