Wing vibration micro-motion characteristic modeling method based on wave equation

The invention discloses a wing vibration micro-motion characteristic modeling method based on a wave equation, which is used for establishing a wing vibration model according to the wave equation aiming at the vibration of a flying wing. When the wing flutters, the displacement amount deviating from the balance position at each moment can be regarded as vibration controlled by a wave equation, the boundary condition of the two ends of the wing on one side is that one end is fixed, the other end is free, and the vibration displacement amount of each point on a wing appearance sweep line is obtained by strictly solving the solution of the wave equation. Therefore, corresponding sweep lines at different moments can be generated, and then new wings after flutter at different moments are obtained. According to the method, the displacement caused by wing vibration is solved based on the wave equation, and the fidelity of micro-Doppler characteristics caused by wing vibration can be improved. The method plays an imp
