通过对磁悬浮快速列车沿线两侧区域振动监测,得出振动级VLzmax与列车速度有较好的相关性,实测得出了振动随车速变化的衰减系数。同时给出了振动随离轨道距离变化的衰减方程,参照现有环境振动国家标准,给出了不同车速下磁悬浮轨道两侧区域的振动达标距离。
Through the monitoring of vibration on both sides of the magnetic levitation rapid trains, the vibration level VLzmax has a good correlation with the train speed, and the attenuation coefficient of the vibration with the vehicle speed has been measured. At the same time, the attenuation equation of the vibration with the distance from the orbit is given. According to the existing national standards of environmental vibration, the vibration standard distances of the two sides of the magnetic levitation track under different vehicle speeds are given.
