摘要
为确定我国200km/h动车组与准高速列车交会空气压力波的大小,从而为动车组安全评估提供依据,在广深线上利用瞬态压力测试系统,对其列车交会空气压力波性能进行测试,并对测量结果进行综合分析.研究结果表明:在线间距为4m、动车组运行速度为200km/h(准高速列车速度为160km/h)时,准高速列车所受到的压力波幅值为1568Pa,而动车组承受的压力波幅值在1400Pa左右;列车头部外形对列车交会压力波幅值有较大影响,控制车外形流线化程度比动力车的流线化程度好,控制车对准高速车造成的压力冲击波幅值小于动力车造成的压力冲击波幅值;对于目前使用的准高速车辆,动车组以200km/h的速度与之交会运行是安全的.
In order to determine the magnitude of air pressure pulse from 200 km/h EMU passing other quasihigh speed train, and to provide the evidence of the safety evaluation of EMU, a ground train test of aerodynamic performance was done using the instantaneous pressure testing system. The results show that under the condition that the space between two lines is 4 m and the train velocity is 200 km/h, the air pressure pulse magnitude of EMU is 1?568 Pa and the other is 1?400 Pa. The configuration of the train head has a great effect on the magnitude of air pressure pulse. Because the streamline configuration of the controlling train is better than that of the power train, the magnitude of air pressure pulse of EMU is lower than that of the power train. That is to say, when the EMU velocity runs at a speed of 200 km/h, the crossing quasihigh speed train is safe.
