超空泡射弹对水雷侵彻的数值模拟

Vulnerability Modeling and Simulation of Sea Mine

以某型水雷为研究对象,通过结构及功能分析、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;分析了超空泡射弹水下侵彻水雷目标的一般过程,建立了水雷等效靶模型;采用AUTODYN完成了水下超空泡射弹对水雷侵彻毁伤过程的数值仿真。仿真结果表明,钨芯射弹在相应临界速度下能够穿透水雷壳体并破坏引信舱内部构件,造成水雷失效。

In this paper, the vulnerability model ture and function of this mine, determination of of some sea mine is established based on analysis of struc-damage level and invalidation tree. The process of super-cavity projectile penetrating into sea mine is described and the equivalent target of sea mine is given. The AUTODYN-based simulation is made, which simulates the penetrating process of projectiles through mine target. The result of simulation proved that lamella of sea mine can be penetrated by tungsten shell and the inner structures of fuze cabin were destroyed at given speed, which result in invalidation of sea mine.
