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。
When a train passes through on steel spring floating slab, intermediate and low frequency noises will be generated in its vehicles. Such noises will reduce the traveling comfort. In this paper, the vehicle＇ s interior noises of floating slab in different tracks are compared and analyzed. The influence of steel spring floating slab track on vehicle＇ s interior noise is analyzed. The results show that the floating slab track with high damping steel spring can effectively reduce the interior noise.
