| Abstract | The design modeling, and benchtop testing of a wing with strain and conventional flap actuation for vibration and flutter suppression is presented. The model hardware is described in terms of the design requirements. The design of an integrated safety system for flutter suppression is detailed. Model components are dynamically tested using an aluminum test article similar to the final design. Ground vibration testing and identification methods are developed using the testbench, and compared to finite element models to validate the analytical modeling. The actual model is tested using an electrodynamic shaker and accelerometers at a grid of points over the structure, and the model is identified using a frequency response-based method. The finite element model of the wing is validated via qualitative frequency response and node line contour comparisons with the identified model, and via quantitative measures of the modal frequencies and the Modal Acceptance Criterion. Finally, the validated analytical model is used for predictions of the aeroelastic behavior of the wing. Thesis Supervisor: Dr. Edward F.
