摘要
为提高某典型聚能射流战斗部的侵彻性能,提出一种基于隔板结构参数优化的性能提升方法。基于TrueGrid与LS-DYNA构建三维有限元模型。利用正交设计法对隔板形状、厚度及罩顶药高进行多因素优化,结合仿真和试验结果,得到侵彻综合性能最优的隔板参数。研究表明,通过增加隔板,同时减少12.81%的装药量,可使射流头部提升28.06%,侵彻性能提升26.62%;经正交优化,得到3组侵彻性能良好的隔板参数,不同参数组合的侵彻深度差异最高达17.72%;钢筋混凝土靶板侵彻试验中,所有优化结构都实现完全贯穿并最大形成0.38CD的背面孔径。隔板形状、厚度与罩顶药高的多参数协同作用显著提高了射流速度与侵彻稳定性,其中锥体-半球组合形状隔板在0.3CD厚度与0.167CD罩顶药高的结构参数综合性能最优,为聚能战斗部工程化设计提供了量化依据。
In order to enhance the penetration performance of a typical shaped charge jet warhead,a structural parameter optimization of the wave-shaper was conducted.To this end,a three-dimensional finite element model was established using TrueGrid and LS-DYNA.Multi-factor optimization of wave-shaper geometry,thickness,and apex charge height was performed via orthogonal design.The determination of optimal parameters for penetration performance was achieved through the integration of simulation and experimental results.The findings indicate that incorporating a wave-shaper led to a reduction in explosive charge mass of 12.81%,accompanied by a significant augmentation in jet tip velocity by 28.06%and an enhancement in penetration performance by 26.62%.Orthogonal optimization yielded three parameter sets that exhibited superior penetration characteristics,with maximum depth variations of 17.72%across configurations.It was observed that all optimized designs achieved complete perforation in reinforced concrete targets,thereby generating maximum backside apertures of 0.38CD(charge diameter).The synergistic effect of wave-shaper geometry,thickness,and apex charge height has been demonstrated to significantly improve jet velocity and penetration stability.The conical-hemispherical wave-shaper,with a thickness of 0.3CD and an apex charge height of 0.167CD,has been demonstrated to deliver optimal comprehensive performance.This provides quantitative guidance for the design of shaped charge warheads.
