连续杆战斗部威力影响因素数值分析

Continuous Rod Warhead Factors Affecting the Power of Numerical Analysis

为研究连续杆战斗部各主要组件对杆环的形成及对战斗部威力的影响,建立了一种典型结构的连续杆战斗部三维有限元模型;利用有限元程序LS-DYNA模拟、分析了连续杆战斗部波形控制器材料、杆条尺寸、连续杆之间排布间距以及主装药材料等参数的变化对连续杆抛撒后分布情况的影响,结果表明:选用酚醛树脂材料波形控制器、填满杆条间缝隙、选用低爆速主炸药、选用高强度材料端盖可提高杆环的完整性和连续性,能为此类战斗部设计提供参考。

In order to study the main components of the continuous rod warhead affect the formation of the ring and the power of warhead, the paper has established the structure of a typical continuous rod warhead of three-dimensional finite element model; To analysis the effect of the material of waveform controller, the section size, the arrangement of rod, as well as material parameters of main charge, such as changes in the final throw of the continuous distribution by the finite element program LS-DYNA. The re- sults show that using the waveform controller of phenolic resin, filling rods between the cracks, The main explosives with low detonation velocity, the cover of high strength materials ,that can improve the integrity and continuity of the ring, It can be able to provide a reference design for such warheads.
