Fluid–structure–control interaction simulation of flutter control problems

Flutter is an aeroelastic instability and can lead to destruction of structures, thus its control important in engineering. A flutter problem classified into fluid–structure–control interaction (FSCI) problems. Conventionally, has been investigated using simple FSCI models. However, these models are sometimes insufficient because their many simplifications (e.g., potential flow, geometry, small deformation). For problems with severe nonlinearity, high-fidelity modeling, where systems incorporated that couple computational structural dynamics fluid dynamics, may be required. Although modeling a high cost, recent improvements machine power have made the use feasible. In analysis, forces dealt as external treated implicitly or explicitly. treatment influences damping controlled systems, it not discussed previous studies on analysis. Furthermore, there no study which simulations were conducted. The present evaluates difference between implicit explicit stability analysis results show cannot capture especially for high-order modes. Therefore, required numerical examples, we consider cantilevered beam axial flow. Control laws designed conventional approaches tested developed Reasonable obtained terms improvement velocity.
