Active flutter suppression technology can greatly expand the flight envelope of aircraft and provide technical support for aircraft weight reduction design. However, it is difficult to carry out the experiments on active flutter suppression technology, and there are great risks to verify this technology in flight test and wind tunnel test. In order to establish a safe and controllable experimental system on active flutter suppression, a virtual experimental verification model for active ground flutter suppression of aircraft wing and wing structure is presented in this paper based on the ground flutter experiment system. In the ground flutter experiment system, the rigid-flexible coupling reduced order model of wing and wing structure is established via Craig-Bampton method. The doublet lattice method is used to establish the generalized aerodynamic force based on the structural mode, and the vibrator is used to provide the excitation force to track the real-time aerodynamic signal. The receptance method is used to establish the active flutter suppression system. The simulation results show that the established virtual experiment platform for active ground flutter suppression can verify the control effect of the control system, and the Active flutter suppression system based on the receptance method can greatly improve the flutter boundary of aircraft wing and wing structure.
