Underwater Acoustic Radiation Prediction Based on Improved SEA Method and Hybrid FE-SEA Method
In this paper improved SEA method and Hybrid FE-SEA method were used to predict the underwater acoustic radiation. The prediction of underwater acoustic radiation results showed a larger error appeared in the shell structure of the first order "breathing mode", when improved SEA method be used. Using the hybrid FE-SEA method to analysis the rigid subsystem that the SEA approach can not handle. The results using hybrid FE-SEA method very accurate in interested frequence.
