摘要
对全国多个大型火车站的列车运行噪声进行测量。利用大量测试数据和专用测试分析软件,分析火车站列车运行噪声特性。对列车进出站噪声分析其时域特性以及鸣笛、轮轨摩擦噪声的频域特性;对列车过站噪声分析噪声时域特性和频率分布范围。所得分析结果对于火车站噪声的声场特性分析及噪声控制有参考价值。
In this paper, noises in several large railway stations in China due to trains running were measured. The testing data was analyzed by means of professional software, and the trains running noise characteristic of railway station was studied. The time domain characteristics of the noise when trains run into and out of the railway station were analyzed. The frequency domain characteristics of trains siren noise and wheel/rail friction noise were also analyzed. The time domain characteristic of noise and its frequency distribution range when trains passed through the railway station were analyzed. The result is valuable for analysis of the sound field characteristics and the noise control in railway stations.
