对于轨道交通而言,减振降噪是首先应该解决的技术问题。目前从设计上这是可以实现的。比如通过降低车厢外表材料的摩擦阻力来降低噪音、车体与轨道之间通过空气弹簧来实现减振等。过去,北京地铁1号线从西单站经过的时候,附近居民家里的杯子都被振下桌子。这种情况现在不会再出现了。减振降噪这个问题已经关注了很多年,成果也不
For rail transit, vibration and noise reduction is the first technical problem to be solved. At present, this can be achieved from the design. For example, by reducing the frictional resistance of the outer surface of the car to reduce noise, body and track through the air spring to achieve such as damping. In the past, when Beijing Metro Line 1 passed from Xidan Station, the cups of the nearby residents’ houses were all shaken off the table. This situation will not happen again now. Vibration and noise reduction this issue has been concerned for many years, the results are not
