中心管三点同步起爆方式对杀伤战斗部毁伤威力的影响

摘要

The damage efficient of the preformed fragments warhead with central tube, which was initiated by three-point initiation, was studied by numerical simulation and verification test. The results showed that, by comparison with the double-point initiation, the method of three-point initiation made the fastest fragments' initial velocity reduced 10.1%, and the slowest raised 8.1%, the warhead's energy could be uniform distributed along the axle. Due to the fragments' dispersion angle increased 32.0%, the range of the damage is increased. Therefore, one three-point initiating circuit was designed and demonstrated by warhead explosion experiment.%对杀伤战斗部在中心管三点同步起爆方式下的毁伤威力进行数值仿真研究及验证试验.结果表明:相同装药结构战斗部条件下,相对于两端点同步起爆方式,采用中心管三点同步起爆方式的破片初速峰值降低10.1%,破片初速最小值提高8.1%,爆轰能量沿轴向得到匀化分布;且破片的飞散角提高32.0%,打击范围增大.静爆试验结果验证了其对毁伤威力的影响.
