摘要：

本文采用现场模态测试与动力学仿真相结合的方法，深入分析 350 km/h 高速铁路运行下穿飞行区时对航

向信标（LOC，localizer）天线阵的振动影响。研究结果表明：在车致振动的影响下，LOC 天线阵在竖向的振动

最为明显，垂轨向次之，顺轨向影响最小；随着隧道埋深的增加，LOC 天线阵的振动响应逐渐减小，其中竖

向振动的衰减幅度最为突出；LOC 天线阵在 37.70 Hz 的频率下容易发生谐振现象；在距离高速铁路线路中

心 0~40 m 范围内，设备机房和 LOC 天线阵的峰值振动加速度迅速衰减,当距离大于 40 m 时，设备机房和

LOC 天线阵的峰值振动加速度衰减速度逐渐放缓；为达到导航设备振动防护要求，建议高速铁路下穿机场

飞行区时 LOC 天线阵与高速铁路线路中心的距离不小于 60 m。

Abstract:

This study employs a combined approach of field modal testing and dynamic simulation to comprehensively analyze

the vibration effects of a 350 km/h high-speed operation railway crossing airport flight area on the localizer (LOC)

antenna array. The results indicate that under the effect of vehicle -induced vibration, the LOC antenna array

exhibits the most significant vibration in the vertical direction, followed by the cross-track direction, with minimal

impact observed in the along-track direction. As tunnel burial depth increases, the vibration responses of the LOC

antenna array progressively diminish, particularly showing the most pronounced attenuation in vertical vibration.

LOC antenna array is prone to resonance phenomena at a frequency of 37.70 Hz. Within the 0-40 m range from the

high-speed railway centerline, both equipment rooms and the LOC antenna array display rapid attenuation of peak

vibration acceleration, while beyond 40 m, the attenuation rate gradually slows. To meet navigation equipment

vibration protection standards, it is recommended to maintain a minimum distance of 60 m between the LOC

antenna array and the high-speed railway centerline when high-speed railway crossing airport flight areas.

Key words:

high-speed railway, airport flight area, localizer (LOC) antenna array, equipment room, vehicle-induced vibration
