摘要：

对CRH3型高速列车在350 km/h运行速度下的气动噪声进行数值模拟.分别搭建受电弓和车厢风洞模型,并采用大涡模拟(LES)计算外部瞬态流场.脉动压力具有偶极子声源特性,可以通过直接边界元法(DBEM)转化为气动噪声.对比分析受电弓的远场气动噪声和车厢的近场气动噪声的频谱特性和分布规律.结果表明：受电弓气动激励集中分布在车厢后端,而车厢气动激励主要作用于不平整的结构表面；前者是一种宽频噪声,在2 000 Hz内均呈下降趋势；后者的频谱在300 Hz以内急剧下降,300～1 500 Hz频段内平缓波动,在1 500 Hz以上呈先下降后上升的趋势；距离受电弓区域越远,受电弓气动噪声占总气动噪声的比重越低.气动噪声结果可用于高速列车的车内噪声预测.
Abstract:

The aerodynamic noise of a CRH3 high speed train was simulated at 350 km/h. The wind tunnel models of the pantograph and coach were constructed respectively, and large eddy simulation (LES) was adopted to calculate the external transient flow fields. The fluctuation pressure possessed dipole source attribute, which could be transferred to aerodynamic noise by direct boundary element method (DBEM). The spectrum characteristics and distribution regularities of the far field aerodynamic noise from the pantograph and the near field aerodynamic noise from the coach were compared. The results show that the aerodynamic noise from the pantograph is a broad band noise with a decreasing trend within 2 000 Hz, which distributes intensively on the trailing end of the car body. The aerodynamic noise from the coach mainly aggregates on the irregular surfaces of the structure, of which the spectrum presents a sharp fall within 300 Hz, an oscillation in 300 1 500 Hz, and a decrease to increase trend above 1 500 Hz. When the distance from the pantograph area goes farther, the proportion of pantograph aerodynamic noise counts lower in the overall aerodynamic noise. The results of the aerodynamic noise can be used in the interior noise prediction of the high speed train．
