Vortex-induced resonance vehicle-mounted active control device for movable bridge

The invention relates to a vortex-induced resonance vehicle-mounted active control device for a movable bridge, the device comprises a load-carrying vehicle and an active control damper on the load-carrying vehicle, the load-carrying vehicle comprises a vehicle body (1), the vehicle body (1) is provided with a limiting rod (5), the active control damper comprises a mass damper (6), a push rod (7) and an accelerometer (9), the limiting rod (5) is embedded into the mass damper (6), and the push rod (7) is connected with the mass damper (6). Compared with the prior art, the truck is loaded with the active control damper to move on the bridge floor, so that damping can act on the position where the vortex-induced resonance inhibiting effect is optimal; the active control damper measures the vibration frequency of a bridge by using an accelerometer, and a push rod is controlled by a control system to push the mass damper to do reverse motion with the corresponding frequency, so that reverse suppression acting forc
