摘要

本文以某流线型钢箱主梁斜拉桥和轨道客运A型车为背景，通过风洞试验研究了风屏障透风率对车-桥系统气动性能的影响。分析试验数据得知：车-桥系统的斯特罗哈数随风屏障透风率增大而减小；当列车处于迎风位置时，风屏障的透风率对车-桥系统斯特罗哈数的影响较为明显；桥梁阻力系数随风屏障透风率的增大而减小，而列车阻力系数随风屏障透风率的增大而增大；随风屏障透风率增大，桥梁和列车升力系数的绝对值均增大；综合考虑列车位置和风攻角等影响因素，风屏障透风率为10%时，列车及车-桥系统在侧风下受到的气动力均较小，有利于行车安全。

Abstract

Based on the streamlined steel box girder cable-stayed bridge and the A type passenger train, this paper studied the effect of wind barrier porosity on train-bridge system aerodynamic characteristic by wind tunnel test. According to the theoretical analysis and experimental data, the Strouhal number of train-bridge system deceased with increasing porosity of wind barrier. With the train located windward, the porosity of wind barrier affected the Strouhal number of train-bridge system obviously. The drag coefficient of bridge deceased with increasing porosity of wind barrier. The drag coefficient of train increased with increasing porosity of wind barrier. The absolute value of lift coefficient of bridge and train increased with increasing porosity of wind barrier. Taking into consideration of the wind attack angle and the position of train, when the porosity of wind barrier was 10%, the aerodynamic force on the train and the train-bridge system were both small, it was suitable for the operational safety of train and wind resistance of bridge structures.
