为研究潜艇双层舷侧在水下接触爆炸作用下的破坏特性和抗爆性能，对潜艇舱段进行等比例实体建模，利用非线性有限元软件LS-DYNA作为工具进行仿真。归纳总结了舷侧主要结构的破坏模式及响应特点，并从吸能的角度探讨了各结构对抗爆性能的贡献度，结果可为结构的强度优化设计提供参考。

To investigate the damage characteristics and anti-shock performance of the double broadside of submarine, this paper performs solid modelling with the equivalent scale of submarine cabin, and carries out the numerical simulation by the nonlinear FVM software LS-DYN. It summarizes the damage pattern and response characteristics of the main structures in broadside, and discusses the contribution of the diverse structures to the anti-shock performance from the viewpoint of energy the absorption, which can provide reference for the optimization design of the structure strength.
