摘要

The SEA and FE model of the hypersonic aircraft model are established based on the SEA and FE theory. Vibro-acoustic response of the aircraft is analyzed by using finite element method and statistical energy analysis. Compared the SEA and FE numerical simulation results with experimental values, there are a little error between them. It shows that the method of finite element and statistical energy analysis arc reliable in the prediction of vibration and noise environment.
