为揭示杀伤元与有防护目标的相互作用机理,基于弹头侵彻防护特点,分析手枪弹侵彻时软防护破坏形式。结合高应变率下超高分子量聚乙烯纤维本构模型,并引入明胶弹性模型,建立手枪弹侵彻带软防护的明胶靶标运动模型。选取9 mm全铜弹(均一硬质结构)和92式5.8 mm手枪弹(钢芯铅柱被甲结构)为杀伤元,对运动模型进行数值计算和实验验证。结果表明,该运动模型能够准确描述手枪弹侵彻带防护的明胶靶标运动过程,可为有防护目标杀伤机理和防护性能研究提供理论参考。 |

The destruction forms of soft body armor penetrated by pistol cartridge are analyzed according to the penetration characteristics of pistol cartridge. A motion model of pistol cartridge penetrating into the gelatin target with soft body armor is established by introducing the fiber constitutive model and gelatin elastic model based on the material constitutive model of ultrahigh molecular weight polyethylene. The motion model is calculated by taking two pistol cartridges with the diameters of 9 mm and 5.8 mm as killer elements. At the same time, the numerical calculation and experimental verification are carried out, respectively. The calculated results are compared with the corresponding experimental results. The compa-rative result shows that the motion model can describe the motion of pistol cartridge penetrating into the gelatin target with soft body armor accurately. |
