| 摘 要： | 在列车经过钢弹簧浮置板地段时，车内产生中低频噪声，影响着人们乘车环境舒适性。通过对不同钢弹簧浮置板轨道地段车内噪声的对比测试，分析钢弹簧浮置板轨道对车内噪声的影响，结果表明采用高阻尼钢弹簧浮置板轨道可有效降低车内噪声。

| Abstract: | In this paper, intermediate-low frequency noise will be generated in the carriage, when the train is on steel spring floating slab, and such noise will reduce the traveling comfort. Through the contrast of vehicle interior noise of floating slab in different track, analyzing intermediate-low frequency noise and rail track vibration reduced influence on vehicle interior noise. The authors hope that this paper can provide a test support for future floating slab track structure design. |
