摘要:
介绍了地铁车辆制动系统因空气弹簧压力急升引起车辆总风欠压所导致的问题，并对供风设备和空气弹簧的原理进行了分析。利用工程系统仿真软件AMEsim对列车制动系统的风源、空气弹簧等主要组成部分进行了建模，得出了不同载荷工况下总风压随载荷变化的仿真气压曲线。通过仿真结果，对地铁车辆空气弹簧气压急升引起的总风欠压问题提出了相应的建议。
Abstracts:
Problems of total wind under pressure caused by air spring pressure rapid rise of metro vehicle braking system are introduced, and the principles of air supply system and air spring system are analyzed. AMESim, an engineering system simulation software, is used to model the air source, air spring and other main components of the vehicle braking system, and the pressure curves of how total air pressure changes as load changes under different working conditions are obtained. Based on the simulation results, corresponding suggestions are put forward for the problem of total wind under-pressure caused by the rapid increase of air spring pressure of metro vehicles.
