摘　　要：会车压力波是影响高速磁浮列车快速、安全和舒适运行的一个重要空气动力学问题。为进一步评估车辆设计,于2003年11月对上海磁悬浮列车在5.1m线间距下的高速会车压力载荷进行了测量,得到了通过列车以400km/h^500km/h的速度运行时引起的会车压力波的大小,同时测量了距离列车侧面0.5m和1.3m处列车风的大小。The pressure load caused by passing maglev vehicles is an important aerodynamic problem, which has great effect on safety and comfort of the vehicles. In order to evaluate the vehicle design further, a field measurement testing was conducted in Shanghai in November, 2003 to investigate the aerodynamic pressure loads on the maglev vehicle. The test conditions were 5. 1m distance between the lines and the speed of passing vehicle varying from 400km/h to 500km/h. In the meantime the train induced airflow speeds were also measured at two positions, 0 .5m and 1.3m, away from the passing vehicle side.
