Embodiment Construction
[0051] The present invention will be further described below in conjunction with the accompanying drawings and specific preferred embodiments, but the protection scope of the present invention is not limited thereby.
[0052] like Figure 7 Shown, the present invention introduces the maglev train of bridge vibration speed-bridge self-excited vibration suppressing method, comprises the steps:
[0053] 1) Obtain the vibration velocity of the bridge
[0054] 2) The suspension control system adopts the suspension control law shown in formula (2) to control the suspension state of the maglev train,
[0055]
[0056] In formula (2), δ(t) is the suspension gap of the electromagnet relative to the bridge, is the vibration velocity of the electromagnet, is the vibration velocity of the bridge, is the vibration acceleration of the electromagnet, k p is the proportional coefficient of the suspension gap δ(t) of the electromagnet relative to the bridge, k d is the vibration ...
