水雷易损性建模与数值仿真研究

摘要

In this paper, a framework of vulnerability assessment of sea mine is proposed. Based on analysis of structure and function of some mine, damage level and invalidation tree, the model of mine vulnerability is established. The numerical simulation is made, which simulates the penetrating process of projectiles in mine. The result of simulation proved that lamella of sea mine can be penetrated by tungsten shell and the structures in fuze cabin were destroyed, which result in invalidation of sea mine.%以水雷为研究对象，提出了水雷目标易损性研究的总体框架；通过对水雷的结构及功能分析、毁伤级别的确定以及构建水雷功能毁伤树，建立了水雷目标易损性模型；完成了水下射弹对水雷侵彻毁伤过程的数值仿真。仿真结果表明，钨芯射弹能够穿透水雷壳体并破坏引信舱内构件，造成水雷失效。
