摘要:
磁浮列车在隧道内交会相比于单列车在隧道内运行会产生更大的压力波动,瞬态压力在变化的同时由车外向车内传递,车内外压力波动可能影响司乘人员舒适性并导致车体气动疲劳损伤。文章基于国内磁浮列车相关技术参数,采用一维可压缩不等熵流动模型的广义黎曼变量特征线法研究了磁浮列车隧道内等速交会时的车内外压力波,确定了在隧道内交会的最不利位置。研究结果表明,在隧道中央等速交会时,车内外压力波动最剧烈。
Abstract:
Compared with single train running in the tunnel, maglev trains crossing in the tunnel will produce greater pressure fluctuation, and the transient pressure is transferred from the outside to the inside at the same time. The pressure fluctuation inside and outside the vehicle may affect the comfort of drivers and passengers and lead to aerodynamic fatigue damage of the vehicle body. Based on the relevant technical parameters of maglev train in China, the generalized Riemannian variable characteristic line method of one-dimensional compressible isentropic flow model was used to study the pressure wave inside and outside maglev trains during trains crossing in tunnel with equal velocity, and the most unfavorable position of crossing in tunnel was determined. The results showed that the pressure fluctuation inside and outside trains was the most severe when the trains met at the tunnel center with equal velocity.
