Embodiment 1
[0040] Embodiment one: this embodiment comprises the following steps:
[0041] 1. On the basis of using the finite element method to solve the dynamic response of the aircraft structure, the finite element model is corrected by the fluid-structure coupling MPCCI or other fluid-structure coupling methods, and the fluid-structure coupling analysis that traverses all flight states and disturbance factors is performed. Aircraft aeroelastic inertia analysis includes harmonic response analysis, random vibration and transient response analysis, and corresponding harmonic response loading, random vibration response and transient response experiments are carried out.
[0042] 2. Calculate the relatively accurate structural dynamic response and obtain the response of each node in the finite element model: due to limited computing resources in actual engineering calculations, the response analysis data obtained by fluid-solid coupling calculations are often not comprehensive enough, but t...
