摘要: 高速磁浮列车通过隧道时会引起剧烈的压力波动,带来乘客耳感舒适性和车体气动疲劳等问题,加大隧道净空面积是显著降低压力波动的基本措施,但也会带来建设成本问题。本文采用一维可压缩非定常不等熵流动模型广义黎曼变量特征线数值模拟压力波的源代码程序,研究了时速600公里速度等级下单列车通过隧道引起的压力波特征,得出了以不同时间间隔舒适性标准为指标的最不利隧道长度,确定了列车动态气密性对最不利隧道长度的影响规律,提出了满足国内外不同舒适性标准的单线隧道净空面积建议值,为补充国内相关技术标准提供了技术依据。
Abstract: High-speed maglev trains will cause severe pressure fluctuations when passing through tunnels, causing problems such as passenger comfort and car body aerodynamic fatigue. Enlarging the tunnel clearance area is a basic measure to significantly reduce pressure fluctuations, but it will also bring about construction cost issues. In this paper, a one-dimensional compressible unsteady non-isentropic flow model is used to simulate the pressure wave by the source code of the charac-teristic line of the generalized Riemann variable. The characteristics of the pressure wave caused by a single train passing through a tunnel at a speed of 600 kilometers per hour are studied. The critical tunnel length with different time interval comfort standards as indicators is obtained. The influence of the dynamic airtightness of the train on the critical tunnel length is determined. The proposed value of clearance area for single-track tunnels that meets different comfort standards at home and abroad is proposed. This provides a technical basis for supplementing relevant domestic technical standards.
