双层集装箱列车通过隧道时,列车受到的空气阻力会显著增大。为了给列车牵引计算提供依据,在遂渝线上对双层集装箱列车过隧道时空气压差阻力进行了实车测量。测试结果表明:双层集装箱车辆进入隧道口时,空气压差阻力急剧上升,之后又迅速回落;测试车处于列车前部、机后第三节车时,平均空气压差阻力比明线空气阻力大80%~95%。 When a double-deck container train passes through a tunnel, the air resistance to the train is significantly increased. In order to provide basis for train traction calculation, real-time measurement of air pressure resistance of double-decked container train passing tunnel was carried out on Suining-Chongqing railway line. The test results show that when the double-deck container vehicle enters the tunnel mouth, the air pressure resistance rises sharply and then drops rapidly again. When the test car is in front of the train and the third car behind the aircraft, the average air pressure resistance is greater than the air resistance 80% ~ 95%.
