Abstract:
Objective: Type selection and properties of train basic brake system can directly affect train operation safety. To tackle this issue, the configuration and features of basic brake system for North America doubledecker electric coach is introduced in detail. Method: The basic brake system forms, tread brake unit features, disc brake unit features and basic brake thermal capacity are analyzed.Result & Conclusion: Stress analysis show that during the drastic changes of brake disc temperature in disc brake system, the stress change gradient is relatively small and brake disc material properties are stable. Thermal capacity analysis results show that wheel tread and brake disc completely can meet the design allowable temperature in the two consecutive emergency brake working conditions. Thus, the basic brake system properties fully meet the requirements for train usage.
