Span cable-stayed active control of flutter
Calculation results can be seen, significantly higher than its control effect to control only the effect of a single AMD is better. Figure 3 AMD critical wind speed and the distance to the central axis curve of 4 Conclusions d / m Figure 4 and AMD to take the initiative to control the distance between the axis of curve 1. In the aerodynamic force is established under the bridge installed AMD three-dimensional equations of motion and the entire bridge AMD equation of motion derived two installation methods on AMD span cable-stayed bridge to wind-induced flutter theory of active control formula, and the preparation of the corresponding computer program. 2. The results show that: AMD is an effective control of large span cable-stayed bridge flutter device,

, it can greatly improve the critical flutter velocity of 3. Installed in the axis of symmetry in a group of AMD, because both control the vertical deck bending movement, but also control the deck around the axis of twist, the control effect than simply movement used to control the vertical bending a single AMD better control, which is indicative of bridge flutter with the movement of vertical bending and torsional motion about the participation of multi-modal coupling the vibration. 4. From the theoretical and computational point of view of the AMD on the active control of bridge flutter its application in practical engineering,
