为分析不同起爆方式下,破片初速沿战斗部轴向的分布情况,进一步研究起爆方式对战斗部杀伤威力的影响。通过理论分析与试验验证,对不考虑起爆方式影响、一端起爆、两端起爆的三种情况进行了分析。结果表明,起爆方式使得破片初速沿轴向的分布不同,战斗部两端的破片初速低于中间部位破片的初速,不考虑起爆方式影响的情况下其杀伤面积计算值最大,考虑一端起爆方式影响的次之,考虑两端起爆方式影响的杀伤面积计算值最小。

To meet the fragment velocity distribution of the warheads axial at different detonation mode, the effect of detonation mode on warhead lethality was further studied. Three conditions which are ignoring detonation mode, the end-initiated, the two ends-initiated were analyzed. The results show that the distribution of fragment velocity is different by detonation mode, the two ends-initiated fragment velocity is lower than middle part, the lethal area is maximum without considering detonation mode, the end-initiate's calculation takes second place, the two ends-initiate's calculation is minimum.
