In this study, the aeroelastic active control of a suspension bridge was studied using both experimental and numerical methods. Two flat plates attached on either side of the suspension bridge were used as the control surfaces. With a suitable rotation of the control surfaces, the turbulent flow around the bridge was modified, thus addressing the problem of aeroelasticity. An appropriate feedback control law was determined using a two-dimensional numerical model. Next, a wind tunnel experiment was conducted to validate the numerical results. The numerical analysis was conducted for a suspension bridge with a span of 3000 m. The effectiveness of the control was considered based on the arrangement of the control wings along the span of the suspension bridge. The ratio between the total length of the control surfaces and the span length was investigated. The coupling of the modes of the suspension bridge also affected the control results. It was suggested that aerodynamic stability could be enhanced by using a partially installed control surface. Moreover, the buffeting responses of bending and torsion of the suspension bridge could be reduced.

在这项研究中，采用实验和数值方法研究了悬索桥的气动弹性主动控制。附在悬索桥两侧的两个平板用作控制面。通过控制面的适当旋转，可改变桥周围的湍流，从而解决了空气弹性的问题。使用二维数值模型确定适当的反馈控制律。接下来，进行了风洞实验以验证数值结果。对跨度为3000 m的悬​​索桥进行了数值分析。根据控制吊翼沿悬索桥跨度的布置来考虑控制的有效性。研究了控制面的总长度与跨度之间的比率。悬索桥的模式耦合也影响了控制效果。建议使用部分安装的操纵面可以提高空气动力学的稳定性。而且，可以减小悬索桥的弯曲和扭转的抖振响应。
