Abstract

In order to ensure the high reliability of aircraft, it is necessary to study the mechanical environment of aircraft. In this paper, the vibration and noise sources of the aircraft in cruise state are sorted out, and the external dynamic load of the typical mission profile of the aircraft is calculated by computational fluid dynamics simulation analysis combined with empirical formula method to obtain the aerodynamic noise load of the aircraft surface. Then, the low frequency response of the aircraft cabin is analyzed based on the finite element method, and the high frequency response of the aircraft cabin is analyzed based on the statistical energy method. The full frequency vibration and noise environment of the aircraft cabin is predicted, and the internal vibration and noise spectrum of the aircraft cabin is obtained. The detailed design method of cabin mechanical environment is established, which lays the foundation for the establishment of complete mechanical environment of the whole aircraft, and also provides a reference for the mechanical environment analysis of aircraft in high mobility and large overload environment.
