摘要:
为研究高速列车表面脉动压力对车内噪声的影响原理,通过小波阈值去噪与相关性系数相结合的方法,提取某线路实测车厢外壁气压信号,得到脉动压力值;采用有限元方法建立中间车体结构、流场以及“结构 - 流场”流致振动耦合模型,分析耦合系统模态频率,并将提取的脉动压力对耦合模型进行冲击加载,分析车体结构位移及车内气压变化情况。结果表明,车窗处振动位移最大,车体结构振动位移与车体结构固有特性以及加载压力频谱特性有关;车内气压级主要集中在 100 Hz 以下的中低频段,车体两侧气压比车内中部气压大,靠近车壁处气压
Abstract:
In order to study the influence mechanism of fluctuating pressure on the interior noise of the high-speed train, thepressure value of the external wall of a train was extracted by the method of combining the wavelet threshold de-noising and thecorrelation coefficient, and the value of the fluctuating pressure was obtained. The finite element method was used to establish thestructure, flow field and the coupling model of flow- induced vibration. The modal frequency of the coupled system was analyzed, and thefluctuating pressure was loaded to the coupling model, and the displacement of the body structure and the change of the internal pressureof high-speed train were analyzed. The results showed that the vibration displacement at the window was the largest, and the vibrationdisplacement of the body structure was related to the inherent characteristics of the body structure and the spectrum characteristics of theloading pressure. The internal pressure level of high-speed train was mainly concentrated in the middle and low frequency section below100 Hz. The internal pressure on both sides of the body was larger than that in the middle part of the body. The pressure near the wall ofthe body was more susceptible to the modal influence of the body structure. The internal pressure level of high-speed train and the modalfrequency of the coupling system were related to the vibration displacement characteristics of the body.
