摘　　要：为了准确获得云爆弹结构对其爆炸威力的影响规律,根据云爆弹的作用原理,设计了中心抛撒药、中心与周边辅助抛撒药2种典型结构的云爆试验装置;采用高速录像和壁面压力传感器,对其静爆试验的威力参数进行了测量和分析.试验结果表明,采用与云爆弹的优化结构相匹配的内壳体,可以显著提高云爆弹的能量利用率和远场超压,提高云爆弹的威力;中心与周边辅助抛撒药结构、钢内壳的试验装置为最佳装置,其火球直径达到30m,平均TNT当量和14m处的TNT当量最大值分别为2.19和3.17.In order to analyze the influence of SEFAE device structure on damage-power,center dispersed and center with circumjacent dispersed SEFAE devices were designed based on explosion characteristics.The static explosion experiments were carried out,and the SEFAE damage power parameters were measured by high-speed photograph and wall pressure transducers.The experiment results show that： the apt inner shell with the optimized SEFAE device structure can increase the utilization rate of SEFAE total energy and the far-field overpressure,so as to improve the damage-power;the center and circumjacent dispersed SEFAE with steel inner shell is the best device with 30 m fireball diameter,and its average TNT equivalent and the maximum TNT equivalent at 14 m were 2.19 and 3.17 respectively.
