Air pressure and comfort study of the high-speed train passing through the subway station
Subway is an increasingly important means of transportation, the influence of the piston effect on the train has attracted extensive attention of researchers. Nowadays, the train speed is increasingly faster, the piston effect caused by the high-speed train is increased accordingly and the pressure fluctuation in tunnel is more complex. In this study, the numerical simulation method is used to study the pressure fluctuation inside and outside the train when the train passes through the tunnel and station. The influence of train speed, mode of the train passing through the station and number of airshafts on the train pressure is analyzed. It is found that both the external and internal pressures of the train increase significantly with the increases of the train speed, and the head carriage bears the most pressure. As the mode of the train passes the station changed, there is a slight variation of train pressure. The airshafts can relieve the pressure inside the train. Finally, passenger comfort under different operating conditions is studied. Different air tightness indexes of the train are compared and analyzed. This study will contribute to the improvement of subway comfort and provide references for the design and operation of the train.
