| 摘 要： | 高速列车通过隧道时会带来乘客舒适性问题。现利用流入、流出相邻两节密封车厢的流量关系,发展了高速空调客车车厢在彼此隔离条件下车外压力引起的车内压力计算方法,模拟了客车在加装风量调节式控制系统时隧道单车压力波与会车压力波条件下的车内压力波动规律,验证了该类系统减缓车内压力的有效性。

| Abstract: | The problem of aural discomfort happens when a high-speed train passes through a tunnel.This paper provides a computer program which is used to calculate the inside pressure caused by the outside pressure of a-high-speed air-conditioned train which is isolated each other based on the flow rate coming in and out of sealed cars,and simulates the inside pressure changes of trains with flow controlled ventilating system.It is proved that this system is effective in reducing the pressure inside of train. |

| Keywords: | high-speed train comfort pressure inside of train |
