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 force is provided for vortex-induced resonance with different frequencies.
本发明涉及一种可移动桥梁用涡激共振车载主动控制装置，该装置包括载重车以及载重车上的主动控制阻尼器，所述的载重车包括车体(1)，该车体(1)上设有限位杆(5)，所述的主动控制阻尼器包括质量阻尼(6)、推杆(7)和加速度计(9)，所述的限位杆(5)嵌入质量阻尼(6)，所述的推杆(7)连接质量阻尼(6)。与现有技术相比，本发明的载重车装载主动控制阻尼器在桥面移动，使得阻尼能够作用在抑制涡激共振效果最佳的位置；主动控制阻尼器利用加速度计测量桥梁振动频率，通过控制系统控制推杆推动质量阻尼做相应频率的反向运动，从而对不同频率的涡激共振提供反向抑制作用力。
