摘要:
目的：列车基础制动装置的选型及性能将直接影响列车的行驶安全，为解决此问题，特介绍了北美双层电客车基础制动装置的配置及特性。方法：对北美双层电客车的基础制动装置形式、踏面制动单元的特性、盘形制动单元特性和基础制动热容量进行了分析。结果及结论：应力分析表明，在盘型制动的制动盘温度急剧变化的过程中，其应力变化梯度较小，制动盘材质性能稳定。热容量分析结果显示，车轮踏面及制动盘在连续2次紧急制动工况下能完全满足设计许可温度。因此,该基础制动装置的性能完全满足列车使用要求。

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.
