###### Abstract
[9], based on the response spectrum analysis method, combined with the design impact spectrum used by the U.S. Navy's DDAM method, calculated and analyzed the impact response spectrum for the research objective of the article. They used the finite element method for calculation and analysis and took the cantilever beam explosion impact as an example to verify the reliability of the numerical method. [PERSON]. [10] systematically summarized various numerical simulation methods in the computational modeling of underwater explosions, focusing primarily on the characteristics of Eulerian and Lagrangian fluid descriptions, Johnson-Cook and Gurson constitutive materials for naval panels, and solving methods such as the Finite Element Method, Finite Volume Method, Boundary Element Method, and Smooth Particle Hydrodynamics. These methods were applied to assess different ship hull materials, with various mathematical approaches and experimental tests conducted for validation. [PERSON] et al. [11] took a certain launching ship as an example and proposed a test method for evaluating the response of the launching platform, as well as tested the maximum structural impact response under the launcher, which gradually attenuated to the bow and stern of the ship. The test analysis showed that the vibration acceleration response was different in different directions, with the highest response in the vertical direction and the lowest in the longitudinal direction. The test results were then verified through finite element numerical analysis. [PERSON] et al. [12] established a coupled model of longitudinal vibration of the thrust shaft system, bearing lubrication, and shaft misalignment, and analyzed the dynamic characteristics of the stern bearing under explosive impact by solving the Reynolds equation and explosive impact equation. [PERSON] et al. [13] studied the impact of waves impacts on the water-lubricated bearings in the propulsion shaft system. By establishing a water-lubricated bearing model that combines the wave impact function, Reynolds equation, and Euler equation, they analyzed the impact of wave impact magnitude, direction, and entry time on the starting performance of the bearing. [PERSON] et al. [14] employed the discrete element method to study the interaction between sea ice and offshore wind turbines, analyzing factors of brittle and ductile failure, and confirmed a strong correlation between self-excited vibration and the brittle-ductile failure of sea ice. [PERSON] et al. [15] investigated the response characteristics of the outer hull of a ship's double-layer panel after being penetrated by an energetic metal jet and subjected to a secondary near-field explosion, using the Coupled Eulerian-Lagrangian method for numerical calculations and validated the analysis through experimental verification. [PERSON] et al. [16], based on strip theory, boundary element methods, and unsteady Reynolds-averaged Navier-Stokes equations, analyzed the wave load results obtained for different ship types under extreme wave motion using various computational methods. They systematically compared the results with experimental data, indicating that numerical methods based on potential theory are consistent with experimental results in small and moderate waves, but exhibit significant discrepancies with measurements in higher waves. [PERSON] et al. [17] took a specific simplified basic structure of a ship as an example and conducted numerical simulation calculations using the dynamic implicit finite element analysis method. Then, based on the MIL-S-901D medium-weight impact standard, they conducted impact tests on three different models. The test data obtained from the medium-weight, high-impact impact machine were compared with the test results to verify the effectiveness of the calculation method. [PERSON] et al.
