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。
Passenger comfort issues arise when high-speed trains pass the tunnel. Now, with the flow of inflow and outflow of two adjacent sealed compartments, the method of calculating the pressure inside the car caused by the pressure outside the car under the isolation condition of high-speed air-conditioners has been developed. The simulation of the tunnel The pressure fluctuation of the bicycle pressure wave and the pressure wave of the meeting car verified the effectiveness of the system in reducing the pressure inside the car.
