Title: Acoustic radiation prediction of multi-compartmental structure based on surface vibration grouping measurement
Abstract: Based on Helmholtz boundary integral equation for calculating underwater radiation of cylindrical shell,a prediction method of acoustic radiation presented by means of surface vibration velocity grouping measurement accomplished by the vibration accelerometers that installed on the shell surface.A complicated multi-compartmental shell structure is designed and the underwater vibration-acoustic radiation experiments with single and multiple excitations are implemented.It shows that the prediction method is accurate and feasible through comparison between the calculating results and the experimental one.Finally the principle of vibration velocity grouping is discussed.
