| Abstract: |
| The work aims to simulate the real situation of aircraft structure subjected to static pressure load and noise load, and provide experimental data for aircraft type selection in the early stage of design. Compressed air was used to carry out static pressure loading, and the combined loading of noise and positive pressure, noise and negative pressure was simulated. Taking static pressure load of 0.6 atmospheres and noise load of 151 dB as examples, the experimental verification was conducted. Under the simultaneous action of noise and static pressure load, if the static pressure load was too large, the structure underwent plastic deformation. The proposed test method of combined loading of noise and static pressure in aircraft selection stage realizes the combined loading of noise and static pressure (positive pressure and negative pressure), and verifies the combined test method of noise and static pressure of aircraft panel structure through the combined test of aircraft panel. |
