地铁列车运行过程中产生的振动会给沿线的建筑和居民带来很大的破坏和困扰。地铁减振控制的对象,主要集中在振源和振动的初始传递对象轨道结构上,从根源入手,降低振源的振动强度,阻碍振动向地基和周围建筑物传递。各种减振器、隔振器以及减振轨道结构,已在地铁减振中得到广泛应用,但减振降噪效果仍达不到预期要求。黏弹性阻尼材料具有优异的阻尼性能,并且在减振钢轨和低噪声车轮上得到了应用,其在地铁道床中的应用,明显提高了道床结构的减振效果,为地铁减振降噪技术提供了新思路。
地鐵列車運行過程中產生的振動會給沿線的建築和居民帶來很大的破壞和睏擾。地鐵減振控製的對象,主要集中在振源和振動的初始傳遞對象軌道結構上,從根源入手,降低振源的振動彊度,阻礙振動嚮地基和週圍建築物傳遞。各種減振器、隔振器以及減振軌道結構,已在地鐵減振中得到廣汎應用,但減振降譟效果仍達不到預期要求。黏彈性阻尼材料具有優異的阻尼性能,併且在減振鋼軌和低譟聲車輪上得到瞭應用,其在地鐵道床中的應用,明顯提高瞭道床結構的減振效果,為地鐵減振降譟技術提供瞭新思路。

The subway's vibrations on operation bring great destruction and obsession to the buildings and residents along the lines. The control objects of subway reducing vibration are mainly concentrated in the vibration source and track structure of the vibration initial transfer object. From the root of the vibration, the vibration intensity of vibration sources is reduced; the vibration transmission to the foundation and surrounding buildings is hindered. All kinds of shock absorber, vibration isolators and vibration reduction track structure, have set up a wide application in the subway vibration reduction, but the vibration and noise reduction effect is less than expected. Viscoelastic damping materials have excellent damping performance, and have been applied in the steel rail and wheels. Its application in the subway track bed obviously improves vibration damping effect of track bed, and provides new ideas to the subway vibration and noise reduction technology.
