| 摘 要： | 通过对地铁车辆内部噪声的测试可知,地铁车辆车内噪声主要以中低频为主,噪声的大小也随着测试位置的变化而不同;在静置状态下,辅助设备运转是主要噪声源,随运行速度的提高,噪声源则主要以轮轨噪声为主。

| Abstract: | After measuring the noise inside metro vehicle,we draw the conclusions that the middle-low frequency noise is serious inside metro vehicle,the value of noise is distinct in different location.The value of serious noise is derived from the running of the equipments in stillness.As the velocity increasing of the metro vehicle,the resource of main noise is changing into wheel rail noise. |
