| Abstract: | Panel flutter is an aeroelastic phenomenon occurring on the aircraft skin.Acting as local structure components on the surface of aircraft,only one surface of panel is subjected to airflow.Because of the special configuration of panel structure,the bending deflection of panel is strongly confined by its geometrical boundaries, and panel flutter usually exhibits nonlinear behavior with limited amplitude which has the same order as the panel thickness.Generally,the panel flutter will cause fatigue damage rathe... |
