摘要
预制破片杀爆战斗部威力的准确评估决定着武器系统对目标打击的有效性和预定毁伤作用的效率,而实现威力准确评估的关键在于预制破片杀爆战斗建模的准确性,其中建模的难点在于对不同预制破片在不同装药类型上的合理、准确排布。针对以上难点,提出一种预制破片杀爆战斗部破片排布方法,在预制破片杀爆战斗部结构分析的基础上,建立了不同破片在不同装药类型的轴向、径向、周向上的排布关系和破片位置坐标数学模型,并采用Visua1 C#语言、DirectX和Direct 3D技术,开发了基于预制破片的杀爆战斗部数字化建模仿真系统,进行仿真验证,结果表明,所提方法实现了不同预制破片在不同装药类型上的快速、准确排布,达到了预制破片杀爆战斗部快速、准确建模的目的,为威力准确评估奠定基础。
The accuracy assessment of the power for preformed-fragment explosives can determine the effective-ness of the weapon system against targeted strike and efficiency of the calculated damage,and is the key to the accu-racy of preformed fragmentation combat modelling.The difficulty lies in the rational and accurate arrangement of dif-ferent preformed fragments on various power charges.For the above challenges,this paper proposes a method for ar-ranging the preformed fragments.Based on the structural analysis of the preformed fragmentation and warhead,a mathematical model of arrangement relationship and fragment position coordinates with the different fragments are es-tablished in the axial,radial and circumferential directions of different charge types.Using Visua1 C#language,Di-rect X and Direct 3D technology,a digital modeling and simulation system based on preformed fragmentation was de-veloped.The simulation results show that the proposed method achieves different preformed fragments on different charge types.This method can perform quick and accurate arrangement,and achieve the purpose of rapid and accu-rate modelling of the preformed fragmentation warhead.
