摘要
在高速列车空气阻力计算中,多竖井隧道的列车空气阻力计算比较复杂,其难点在于多竖井的活塞风计算。本文试图通过建立双竖井隧道的活塞风计算公式,以解决双竖井隧道空气阻力计算的困难。
It is very complex to calculate the aerodynamic drag of high-speed train running in railway tunnel with multi -shafts .And the difficulty is to calculate the velocity of piston wind. This paper attempts to establish a calculating formula of piston wind velocity in tunnel with double shafts to solve this problem.
