为有效缓解高速列车穿越全封闭声屏障时产生的微气压波对声屏障周围环境的影响,采用数值模拟计算的方法,对列车通过不同开口率的全封闭声屏障所产生的压力变化和微气压波进行研究。得出声屏障在不同开口率作用下的微气压波波形,对比分析,得出声屏障的最优开口率。
In order to effectively alleviate the impact of micro-pressure waves generated by high-speed trains passing through the fully enclosed sound barrier on the ambient environment of the sound barrier, the numerical simulation calculation is used to analyze the pressure changes and the micro-pressure generated by the fully enclosed sound barrier with different aperture ratios Wave research. Obtained the sound barrier under different aperture ratio under the action of micro-pressure waveforms, comparative analysis, the optimal aperture ratio of the sound barrier.
