摘要
瞬变压力对旅客乘车舒适度的影响是设计高速铁路隧道必须考虑的重要问题。列车内空气压力的瞬变程度不仅取决于隧道净空断面积,而且同车辆的密封性能有密切关系。文章根据现场实测资料从数学模型出发,对车辆密封性能和瞬变压力从车外向车内传递规律进行了研究,根据车内气压响应计算给出了"折减系数"的计算表格和经验公式。
Air pressure fluctuation inside the train affecting passenger comfort depends not only on tunnel cross section but also the airtightness of carriages. Utilizing mathematical model and in-situ measurement data, authors carried out research work on the airtightness of carriages and the law of transient pressure penetrating the train and transferring into it. According to the air pressure response inside the train, calculated reduction coefficients and empirical formulas are given in this paper.
