摘要

针对反恐处突、特警突击等场景中高效破除门锁的作战需求

为解决传统刚性弹丸附带损伤控制不足的技术难题

研发基于金属粉末复合介质的低附带损伤破除门锁弹药

并通过实验、仿真与理论分析系统研究其性能。以W/Pb/Fe金属粉末与石蜡为核心原料

设计并制备基础试样(试样Ⅰ)及“碳纤维外封装”(试样Ⅱ)、“3D打印骨架内嵌+碳纤维外封装”(试样Ⅲ)2种增强试样

通过实验、理论分析与数值仿真研究其性能。单轴压缩实验结果表明

试样Ⅲ(22.72MPa)与试样Ⅱ(15.47MPa)的峰值强度分别为试样Ⅰ(4.77MPa)的4.76倍与3.24倍

且三者均呈现“初始压缩钝粗-屈服微裂-滑移损伤-压致拉裂”4阶段失效特征。弹道测试实验结果表明

发射2发试样Ⅲ弹丸可使门锁4个锁舌全部脱落

毁伤效能显著优于其他2种试样。基于Mie-Grüneisen方程与SPH方法建立的仿真模型

较好地预测了试样应力演化与失效形貌

仿真与实验von Mises应力峰值误差<0.3%。构建的综合易损性指标可完整表征材料损伤特性

为复合介质弹丸结构优化和选型提供理论与数据支撑。

Abstract

In response to the need for efficient breaching of door locks with minimal collateral damage to surrounding personnel and facilities in scenarios such as counter-terrorism operations and SWAT assaults

this study addresses the technical challenge of inadequate collateral damage control inherent in traditional rigid projectiles.We developed a low-collateral-damage door lock-breaching munition based on a metal powder composite medium and systematically investigated its performance through experiments

simulations

and theoretical analyses.Using W/Pb/Fe metal powders and paraffin as core materials

we designed and fabricated a baseline specimen (Specimen Ⅰ)

as well as two reinforced specimens:“carbon fiber external encapsulation” (Specimen Ⅱ) and “3D-printed skeleton embedded+carbon fiber external encapsulation” (Specimen Ⅲ).Their performance was studied using experiments

theoretical analyses

and numerical simulations.Results of uniaxial compression tests show that the peak strengths of Specimen Ⅲ (22.72MPa) and Specimen Ⅱ (15.47MPa) are 4.76 and 3.24 times that of Specimen Ⅰ (4.77MPa)

respectively

with all three exhibiting a four-stage failure mode:“initial blunt compression-microcrack yield-slip damage-compression-induced tensile cracking.” The ballistic test results indicated that firing two Specimen Ⅲ projectiles completely disengaged all four lock bolts

demonstrating a significantly greater destructive efficiency than the other two specimens.The simulation model

established using the Mie-Grüneisen equation and SPH method

accurately predicted the stress evolution and failure morphology of the specimens

with a simulation-to-experiment von Mises stress peak error of less than 0.3%.The constructed comprehensive vulnerability index fully characterizes the damage properties of a material

providing theoretical and data support for the structural optimization and selection of composite medium projectiles.
