| Abstract: | To explore the problem of aeroelasticity of flexible wing, the engineering aeroelastic modeling and structural dynamics analysis method were studied. By using aeroelasticity theory and method, structural modeling with FEM, structural dynamics and vibration mode were analyzed, and then problem of gust load alleviation for a large flexible wing was discussed. For a large flexible wing, structural modelling was set up and collaborative simulation of structural dynamics and movement were performed by using of software CATIA, MSC.adams and MSC.nastran. The simulation verifies the approach available and effective. |
