战斗部轴向双环起爆数值仿真及试验研究

Numerical Simulation and Experimental Study on the Warhead Initiated by Double-ring Explosive Train

对典型中心管预制破片战斗部在轴向单环起爆与轴向双环起爆两种方式下的毁伤效能进行数值仿真研究,结果表明:相比于单环起爆,战斗部轴向双环起爆可以提高破片初速和调整爆轰波形。据此,设计了"一入两出"的战斗部轴向双环起爆网络,并进行战斗部静爆试验。试验结果与仿真结果相差小于5%,同时验证了该起爆网络的作用可靠性和实用性。

The damage efficiency of two typical preformed fragment warheads with central tube, which were initiated by one ring initiation and double-ring initiation circuit respectively, was studied by numerical simuiation. By comparison with the one ring initiation warhead, the initial velocity of fragments was increased by double-ring initiation, as well as its detonation wave was adjusted. Meanwhile, one practical double-ring booster circuit was designed and demonstrated by warhead explosion experiment. The results show that the difference between test result and simulation result was less than 5%, and the reliability and practicality of double-ring booster circuit was verified.
