摘　　要：为获得小钨球对防弹衣加人体等效靶的侵彻性能,对小钨球侵彻Ⅲ级软体防弹衣加25 mm厚红松靶进行了试验研究。在此基础上,结合小钨球侵彻LY-12硬铝靶试验与数值模拟,研究了LY-12硬铝靶与Ⅲ级软体防弹衣加25 mm厚红松靶之间的等效关系,并通过量纲分析方法建立了小钨球侵彻Ⅲ级软体防弹衣加25 mm厚红松靶的弹道极限预测公式,分析了小钨球质量变化对其侵彻性能影响的规律。结果表明:对于小钨球的侵彻,Ⅲ级软体防弹衣加25 mm厚红松靶可等效为6.2 mm厚LY-12硬铝靶;弹道极限预测公式的预测值与试验值吻合良好,并且随着钨球质量的增加,弹道极限近似服从幂函数递减规律。研究结果对单兵破片战斗部的改进设计具有一定的参考价值。In order to study the penetration performance of small tungsten spheres on the human equivalent target with body armor,the test of small tungsten spheres penetrating 25 mm thick pine target with Class Ⅲ soft body armor is carried out.On this basis,the equivalent relationships between 25 mm thick pine target with Class Ⅲ soft body armor and LY-12 hard aluminum target are studied by combining the experiment and numerical simulation of small tungsten spheres penetrating LY-12 hard aluminum target.According to the method of dimensional analysis,the ballistic limit prediction formula of small tungsten spheres penetrating 25 mm thick pine target with Class Ⅲ soft body armor is established and the influence of the mass change of small tungsten spheres on the penetration performance is studied.The experimental results reveal that for the penetration of small tungsten spheres,a 25 mm thick pine target with Class Ⅲ soft body armor can be equivalent to a 6.2 mm thick LY-12 hard aluminum target.The predicted value of ballistic limit prediction formula is in good agreement with the test value.And with the increase of the mass of tungsten spheres,the ballistic limit approximately obeys the law of decreasing power function.The research results have certain reference value for the improvement and design of individual fragment warhead.
