Statistical energy analysis (SEA) can accurately describe the average vibration characteristics through system energy flow and transmission feedback.
It is a powerful tool to solve the problem of high-frequency acoustics-vibration.
SEA is widely used in vehicles, ships, aviation, and other transportation engineering fields.
However, the expansion of SEA, based on the assumption of modal equipartition and weak coupling, is limited to the intermediate frequency.
Although the SEA basic theory can be extended by relaxing the hypothesis conditions or the analysis of the medium-frequency acoustics-vibration can be carried out using the finite element method (FEM) and SEA mixing method, there are still many challenges associated with these options.
To improve the basic theory of SEA and knowledge of intermediate frequency extension methods, as well as attract the attention of domestic scholars, this paper describes classical SEA and intermediate frequency extension methods.
First, coupling loss factor (CLF) error propagation and parameter acquisition in classical SEA are introduced, and the three relative error calculation methods of CLF are compared.
Then, the method of obtaining parameters is described from three aspects of energy transfer, input load, and modal density.
Second, SEA intermediate frequency extension technology (experimental statistical energy analysis (ESEA), finite element statistical energy analysis (FE-SEA), statistical modal energy distribution analysis (SMEDA), and waveguide analysis (WGA)) are introduced.
Neutron structure assembly and modeling, interval and mixed interval analysis, interval variable and mixed interval variable response are also described, so as to justify the development of a hybrid, large-scale interval algorithm.
Finally, the engineering application of the above method is introduced, the limitations and shortcomings of SEA and intermediate frequency extension methods are reviewed, and unsolved problems are further discussed.
