摘要
介绍了某A型地铁车辆空气弹簧供风系统仿真建模方法,对该型车在典型停站工况下的充排风时间进行了仿真计算,得到了空气弹簧系统停站过程中的压力-时间历程曲线,探讨了不同工况下空气弹簧的充排风时间,并给出了相关建议。
The simulation modeling method for the air supply system for air springs on a certain A type metro vehicles is described.Simulation calculation is made for the air charging and discharging time of the vehicle under typical working conditions of being stopped at station.The time history curve of pressure change of the air spring system in the process of vehicle stopping at station is obtained.The air charging time and discharging time of air springs under different working conditions are discussed.And relevant suggestions are given.
