| The paper aims to realize the simulation and prediction of the control surface impulse excitation response of flutter flight test. A simulation method of control surface impulse excitation response was proposed. Based on the finite element model of aircraft structure dynamics, the aerodynamic model of flutter flight test and the impulse excitation force model of control surface were established. Based on the above models, the simulation model of control surface impulse excitation response of flutter flight test was established to realize the simulation of control surface impulse excitation response. Firstly, the simulation model of control surface impulse excitation response of single wing with aileron was established. The simulation analysis of excitation response was conducted, and the structural response amplitude was obtained. The simulation analysis of the control surface impulse excitation response of the whole aircraft model is carried out. The simulation results are compared with the flight test results. The two results are basically consistent, verifying the effectiveness of the method. |
