摘要
高速列车进出隧道时会产生一系列空气动力学效应,引起噪声及车厢内压力的变化.实验测试是研究这一问题的有效方法之一.利用高速列车空气动力学模型实验系统对高速列车在进入隧道过程中瞬变压力的传播规律进行研究,并分析了列车速度以及阻塞比对测试结果的影响,得出的结论对以后的研究具有一定的参考和借鉴.
When high-speed train enters into a tunnel, a series of aerodynamics effects such as pressure variation in carriage noises were created. Model test is an efficient method to research pressure variation. In this paper, using high-speed train aerodynamics model research system, the propagation mechanism of compression wave, which created when high-speed train entering into a tunnel was researched, at the same time the effect of velocity of the model train and the ratio of train with tunnel was analyzed, the result is helpful for future research.
