The invention discloses a maglev train track resonance identification method and system, and the method comprises the steps: obtaining at least one track resonance related signal, and extracting a track resonance characteristic signal from the track resonance related signal; identifying the resonance condition of the maglev train track by comparing the characteristic quantity related to the train track resonance characteristic signal with a preset resonance judgment threshold value, and optimizing the parameters of a levitation controller to avoid continuous train track resonance when the identification result shows that the train track resonance occurs. The method can effectively judge the track resonance, is high in identification accuracy, does not need to increase any hardware cost, is simple to implement, can be embedded into a suspension control system, and can automatically inhibit the track resonance phenomenon.

    本发明公开了一种磁浮列车车轨共振辨识的方法和系统,包括:获取至少一个车轨共振相关信号,并从所述车轨共振相关信号中提取车轨共振特征信号;通过与所述车轨共振特征信号相关的特征量与预设的共振判定阈值进行比较,辨识所述磁浮列车车轨的共振情况,当辨识结果显示发生车轨共振时优化悬浮控制器参数以避免出现持续车轨共振。本发明可以有效判断出车轨共振,且辨识准确性很高,且不需要增加任何硬件成本,实现简单,能够嵌入到悬浮控制系统中,并能够自动抑制车轨共振现象。
