建立包含4个独立的悬浮闭环控制的低速磁浮列车单悬浮架动力学模型,仿真分析悬浮架的耦合效应。结果表明,悬浮架在低频段具有较好的解耦性能,但在稍高的某频段内则具有显著的耦合作用。耦合作用是由于悬浮架的几种共振模式引起的,其频段和耦合幅值与控制参数和结构参数有关。
建立包含4箇獨立的懸浮閉環控製的低速磁浮列車單懸浮架動力學模型,倣真分析懸浮架的耦閤效應。結果錶明,懸浮架在低頻段具有較好的解耦性能,但在稍高的某頻段內則具有顯著的耦閤作用。耦閤作用是由于懸浮架的幾種共振模式引起的,其頻段和耦閤幅值與控製參數和結構參數有關。

The dynamic equations of one bogie of the low-speed maglev train were built,which involved four de-centralized closed-loop controls for magnetic levitation.Simulation results indicate as follows:In the bogie,the four controlled points can decoupled in low frequencies and coupled in high frequencies;coupling is caused by several modes of resonance of the bogie and the frequency ranges and coupling amplitudes are related to control parameters and structural parameters of the bogie.
