| 摘 要： | 使用多通道噪声分析系统,对中低速磁悬浮列车运行时产生的噪声进行信号采集及分析,取得其传播规律、频谱等特性,并与普通轮轨噪声进行对比。研究结果表明,中低速磁悬浮列车运行时相对于普通轮轨噪声较低,就声环境保护角度而言具有较大的优势。

| Abstract: | Multi-channel noise analysis systems are used to obtain the noise properties of the middle -low-speed maglev vehicles, icluding the noise propagation property and the spectrum property.It is shown that the middle-low speed maglev vehicles used for city transportation has advantage over the wheel-rail as far as sound environment protection is conserved. |
