| 摘要: |
| 为了研究导弹战斗部(柱壳装药)在破片场中的累积毁伤问题,在现有单破片起爆平板装药的Jacobs-Roslund经验准则的基础上,分别建立了考虑破片尺寸、破片撞击角度、柱壳装药的装药半径和壳体厚度的单球破片、双球破片冲击柱壳装药临界起爆条件的工程分析模型。该模型计算结果与数值模拟结果和现有试验结果相吻,证明利用该模型能较准确地预测单球破片、双球破片以任意角度冲击柱壳装药的临界起爆条件。 |

| Abstract: |
| In order to investigate the shock initiation of missile warhead (cylindrical covered charge) by multiple fragments impact under actual combat conditions, based on Jacobs-Roslund formula of single fragment initiation plane covered charge, the engineering calculation model of the impact critical initiation condition of cylindrical covered charge with single or double spherical fragments were established. The calculation model includes several parameters, such as fragment diameter, impact angle, charge radius and shell thickness. The calculation model results were in good agreement with the simulation results and experimental results, which proves that the calculation model can provide a better prediction of the impact critical initiation condition of cylindrical covered charge with single or double spherical fragments. |
