| Abstract: |
| Objective To design a vibration fixture of a special shaped aircraft. Methods Firstly, the finite element modal simulation calculation and the uniformity simulation calculation were carried out for the preliminary design of the vibration fixture. The vibration fixture was improved based on the simulation results. By calculation, the fixture after design improvement met the design requirements on frequency and uniformity. Results There was an error of 7% between the natural frequency test result of the fixture and simulation calculation. The uniformity was also consistent. Conclusion The result of simulation calculation is correct and the design is reasonable. The transfer characteristic of the fixture is good. |
