摘要
针对地铁列车在隧道内的运行特点,采用FLUENT(6.3.26)三维模拟软件,在列车最高运行速度120 km/h的条件下,对列车进出隧道洞口、在隧道内匀速运行、进出站及加减速运行、经过中间风井等多个运行场景的压力波及压力变化率进行模拟分析,提出地铁列车在隧道内运行压力波和压力变化率规律,以及在给定压力舒适度标准下的最大隧道阻塞比。
Based on the characteristics of subway trains run- ning in tunnel, the pressure waves and maximum pressure gradient of several running scenarios were studied in the paper. The pressure waves and maximum pressure gradient for trains passing by the ttmnel entrance, running in the tunnel with a speed of 120km/h, with an accelerated speed or decelerated speed, and passing by the tunnel with an air shaft have all been simulated and analyzed with the help of the commercial software FLUENT （6.3.26）. Finally, the blockage ratio under selected pressure amenity standard has been proposed.
