Experimental verification of ship vibration and noise based on the Statistical Energy Analysis method

摘要

This study analyzes the acoustic radiation characteristics of stiffened cylindrical shells from physical tests and numerical simulations. The basic method of measuring the acoustic radiation test of the underwater cylindrical shell is mastered, the underwater acoustic radiation distribution is tested, and the numerical simulation of the acoustic properties of the stiffened cylindrical shell is studied by designing the vibration model test of the stiffened cylindrical shell. Through the above test and numerical analysis can be concluded as follows: (1) In this study, we have mastered the technology of the acoustic vibration test of the stiffened cylindrical shell, established and formed the underwater acoustic radiation testing method, and laid the foundation for the underwater acoustic radiation characteristics testing method of the ship by designing the stiffened cylindrical shell model test.
