摘要

列车高速通过隧道过程中诱发了隧道内剧烈的压力波动，同时也引发了乘务人员和旅客的耳部不适感，由此产生了高速列车车内压力舒适性环境的问题。本文采用线路实车试验方法，获得了特定线路下350 km/h中国标准动车组通过隧道时车内外压力变化特征。以车内每1 s、3 s、10 s和60 s内最大压力变化量作为描述压力舒适性环境的参数变量，对其时间历程特征进行研究，开展了线路坡度、隧道长度、列车速度和“隧道群”对车内压力舒适性环境影响特征分析，并探讨了整车气密效率与车内人员耳部不适性的关系。研究结果为进一步认识高速列车压力舒适性环境及其设计与控制方法的研究提供了较好基础。

Abstract

Strong pressure fluctuations are induced when the train passes through the tunnel at high speeds

which causes aural discomfort for passengers and crews

known as the internal pressure comfort environment problem. In this study

field tests are carried out to obtain the internal and external pressure variation characteristics of the 350 km/h China Standard EMU (electric multiple unit) passing through the tunnels on a specific line. The pressure comfort environment is described using the internal maximum pressure variation within 1 s

3 s

10 s and 60 s

i.e. Δ

/1s

/3s

/10s and Δ

/60s

and the time history characteristics are investigated. Influence of the line slope

tunnel length

train sp

eed and “tunnel group” on the internal pressure comfort environment are analyzed

and the relationship between the sealing efficiency of the train and the aural discomfort is discussed. The results provide a good foundation for further cognizing high-speed trains’ pressure comfort environment as well as its design and control.
