Modelling and Control of a Suspended-Span Bridge Section
| Description | The work in the grant is directed to the use of feedback control in combination with movable leading- and trailing-edge flaps in the suppression of flutter and buffeting in long-span suspension bridges. The work contains both theoretical and experimental elements - with the experimental work carried out in wind tunnels at Imperial College and BMT. It was found that both flutter and buffeting could be suppressed with a controllable trailing-edge flap, while the wind speed associated with instability in the torsional divergence mode could only be elevated using a leading-edge flap. More detail appears in the publications associated with this grant. |
| Exploitation Route | Much of the theory developed can be adapted to things such as the control of wind turbine blades. |

| Description | This work studied the use and efficacy of leading and trailing edge flaps in the suppression of flutter and buffeting in long-span suspension bridges. Theoretical results were tested experimentally at Imperial College and at the consultancy BMT who were interested in the results in relation to their own bridge design work. This work has also found its way into wind turbine control in relation to wind power generation. |
