| 摘 要： | 采用Artemis测试分析系统对隧道内运行的大连厂地铁车辆进行噪声测试,在地铁车辆内选择了六个测试点,通过对测试数据的分析、讨论.并对测试数据进行了分析,结果表明：地铁车辆运行时,车辆内噪声的最主要的噪声源是轮轨噪声.噪声级随着地铁车辆的速度的增加而增加.主频带一般都在315～5 000 Hz之间.低频率的声压级很小.研究地铁车辆内的噪声特性只需研究中高频声压级.

| Abstract: | With the Artemis test and analysis system,six test places were selected in the vehicles to test the noises when driving in the tunnel.The features of these noises were studied after analyzing and discussing the statistics.The main noises in underground driving are from wheels and tracks.The higher the speed is,the higher the noise levels is.Dominant frequency is usually between 315 ～5 000 Hz,and the SPL of low frequency＇s is very low.Thus,the noises which are supposed to study are the ones with high and medium SPLs. |
