摘　　要：随着城市轨道交通的快速发展,噪声与振动问题日益严重,亟需精准的控制方案。提出了基于实时监测的轨道减振降噪方案,通过振动源智能识别、自适应减振参数优化和协同降噪控制三大环节,实现了列车运行中的动态振动噪声控制。实验结果表明,该方案有效降低了轨道振动及车厢内噪声,500~1000 Hz频段噪声降幅达7.9 dB(A),验证了方案的实用性和高效性。With the rpaid development of urban rail transit,noise and vibration problems are becoming increasingly serious,and precise control solutions are urgently needed.This paper proposes a track vibration and noise reduction scheme based on real-time monitoring,which achieves dynamic vibration and noise control during train operation through three major links:Intelligent identification of vibration sources,adaptive vibration reduction parameter optimization,and collaborative noise reduction control.The relevant experimental results show that this scheme effectively reduces track vibration and cabin noise,with a noise reduction of 7.9 dB(A)in the 500~1000 Hz frequency band,verifying the practicality and efficiency of the scheme.
