基于球形、平头圆柱和立方块破片撞击带钢壳炸药的模型,采用数值模拟方法,研究了带壳炸药受破片冲击起爆的基本规律,给出了带壳炸药冲击起爆的阈值速度.结果表明,除了破片几何尺寸和质量外,破片着靶姿态对冲击起爆阈值速度也有明显影响,尤其是立方块破片.

Based on the model of the covered charge impacted by spherical fragments, flat-nose cylindrical fragments and cubic fragments, the impact mechanism was studied by numerical simulation. The impact threshold velocity was proposed. The result shows that the impact orientation to target is an important factor affecting impact threshold velocity as well as the shape and mass of fragment, especially for the cubic fragment.
