摘要
为探明速度140 km/h的中低速磁浮列车在双线隧道内交会时隧道壁面和车体表面压力变化情况，文章采用数值计算方法研究了车/隧不同参数对隧道壁面和车体表面气动性能的影响，并对比了不同编组长度的列车和不同隧道净空面积对列车车内压力的影响。研究结果表明，4车编组的磁浮列车在双线隧道中部交会时，隧道壁面测点的压力变化峰峰值与隧道净空面积的1.379次方成反比，车体表面压力测点的变化峰峰值与隧道净空面积的1.231次方成反比。当隧道净空面积为66.2 m

时，在气密性指数为0.5 s条件下，8车编组列车在隧道内交会引起车内测点的3 s压力变化值相较于4车编组列车增加102.2%，而在气密性指数为8 s条件下该比例降低至50.4%。文章的研究结果可为中低速磁浮隧道工程建设提供参考依据。
Abstract
In order to investigate pressure variations on both the tunnel wall and train body surface when 140 km/h medium-low-speed maglev trains intersect in two-track tunnels
numerical calculations were performed
focusing on the effects of different parameters of the train/tunnel on the aerodynamic performance of the tunnel wall and train body surface. Moreover
a comparison was conducted across different train consist lengths and various tunnel clearance areas to assess their effects on internal train pressures. The results indicated an inversely proportional relationship between the peak value of pressure variations at measuring points on the tunnel wall and the 1.379th power of the tunnel clearance area
as well as between the peak value of pressure variations at measuring points on the train body surface and the 1.231st power of the tunnel clearance area during the intersection of 4-car maglev trains in the middle section of two-track tunnels. Additionally
under an airtightness index of 0.5 s
the pressure variations over 3 s at measuring points inside 8-car trains
resulting from the intersection in tunnels with a tunnel clearance area of 66.2 m
2
increased by 102.2%
compared with the 4-car scenarios. Under an airtightness index of 8 s
this figure decreased to 50.4%. The study findings of this paper provide a reference basis for the construction of tunnels to accommodate the operation of medium-low-speed maglev trains.
