AB  - Acoustic radiation and propagation characteristics of underwater elastic structures are an organic whole, 
which should be considered comprehensively. Based on the three-dimensional sono-elasticity theory of 
ships, the integrated calculation method of acoustic radiation and propagation in ocean environment is 
realized by using the simple source boundary integral equation. The correctness and accuracy of the method 
are verified by a series of examples. Based on the domestic supercomputer platform, the parallel 
transformation of the algorithm is completed, and the two-level multi-core parallel is realized, which greatly 
improves the computing efficiency. The application of acoustic radiation calculation in composite structures 
is carried out. This calculation method can not only provide guidance for low noise optimization design of 
underwater elastic structures, but also lay a foundation for real-time calculation of radiated sound field in 
ocean environment.
