| Abstract: |
| The work aims to quickly realize the vibration environment prediction of the whole process and whole space of aviation equipment. The vibration environment prediction method based on the combination of measured data analysis and simulation analysis was theoretically derived, and the feasibility of the theoretical method was verified by ground tests. On this basis, with a UAV as an example, combined with the measured vibration data analysis and simulation analysis results, the combined vibration prediction method was applied. This method realized the prediction of the vibration environment in the whole process and the whole space, and provided an effective and convenient method for the rapid prediction of the vibration environment. The vibration environment prediction method combined with measured data analysis and simulation analysis can realize the prediction of the vibration environment in the whole process and whole space of the aircraft, and greatly reduce the calculation time, which provides a convenient and effective method for the digitization of the vibration environment of aviation equipment. |
