Analysis of Aeroacoustics Characteristics for Pantograph of High-Speed Trains

摘要

摘要: 为研究高速列车受电弓气动噪声源分布及频谱特性,利用计算流体力学原理对高速列车受电弓流场进行计算,获得了受电弓表面脉动压力;在此基础上,利用FW-H方程计算高速列车受电弓远场气动噪声.计算结果表明:高速列车受电弓远场气动噪声具有较为明显的指向性,其指向性基本上不受列车速度的影响;远场监测点总声压及在10~20附近达到最大.受电弓气动噪声的总声压级随着列车速度的增加而显著增大;受电弓远场气动噪声具有明显的主频,且随着列车速度的增加,远场气动噪声的主频也增大;受电弓顶部横梁是引起受电弓气动噪声的主要因素.

Abstract: In order to study aerodynamic noise source distribution and frequency spectrum for the pantograph of high-speed trains, the flow field for the pantograph of high-speed trains was calculated using the computational fluid dynamics method, and the fluctuating pressure on the surface of the pantograph was obtained. On this basis, the far-field aerodynamic noise for the pantograph was computed using the FW-H equation. Computational results show that the aerodynamic noise for the pantograph of high-speed trains has obvious directivity, which is not affected by the train speed, and the total sound pressure level of the far-field measurement points reaches the maximum near the 10~20. Moreover, the total sound pressure level increases significantly with the train speed. The far-field aerodynamic noise has obvious main frequency that increases with the train speed. The beam at the top of the pantograph is a main contributor to the aerodynamic noise for the pantograph.
