Vibration and sound radiation for large underwater structures

Radiated noise is an important index for evaluating the operational performance and ability of survive of submarines and also the main factor to destroy the acoustic stealth performance. Prediction of the vibration and sound radiation of underwater structures is an important basis of vibration and noise reduction designing. Prediction of the vibration and sound radiation of underwater structures is an important basis of vibration and noise reduction designing. Therefore improving the computational efficiency of sound and vibration prediction of large underwater structures without losing accuracy is of great significance for the development of submarine acoustic stealth technology.
