Summary

 
Object and purpose of research. This paper discusses vibroacoustic parameters of engineering structures in a wide frequency band. The purpose of the study is to select a numerical method in terms of the maximum convergence between analytical and experimental data for both higher and lower frequencies.
Subject matter and methods.The paper discusses numerical simulation methods (FEM, SEA, hybrid) for vibroacoustic parameters of engineering structures. Experimental vibroacoustic measurements were performed in a small-size tank on a fullscale model of a double-hulled structure.
Main results. The study concludes that hybrid method is the most suitable in terms of sufficient calculation speed and accuracy of results for vibroacoustic parameters in a wide frequency band.
Conclusion. Application of hybrid simulation method to vibroacoustic parameters pointed out the possibility of studies on large models in a restricted space of small-size tank for medium and low frequencies.
