摘要: 定向起爆技术可大幅提高鱼雷战斗部的能量利用率, 加大对大中型舰船目标的毁伤。基于此, 对重型鱼雷定向战斗部缩比样机在3种不同起爆方式下, 在相同测点处的冲击波超压进行仿真计算和试验测试, 结果表明, 战斗部3点偏心起爆方式产生的冲击波超压在一定范围内, 在目标方向上较中心起爆方式有所增强, 偏心距愈大, 冲击波超压增强幅度愈大。因此, 3点偏心起爆可作为重型鱼雷定向战斗部优先选择的起爆方式。该文的研究将为优化重型鱼雷战斗部设计提供参考。Abstract: Directional initiation technology can increase the power utilization ratio of directional warhead for a torpedo, and enhance the damage to large ship target. In this study, numerical simulation and experiment were conducted to investigate the shock wave overpressure of the scale-reduced prototype of heavyweight torpedo directional warhead at same testing point in three different initiation ways. The results show that in certain distance range, the 3-point eccentric initiation of the warhead generates higher shock wave overpressure in the direction of target than central initiation, and the shock wave overpressure increases significantly with the increase in eccentricity. Therefore, the 3-point eccentric initiation becomes the preferential initiation way for heavyweight torpedo directional warhead. This research may provide a reference for optimization design of heavyweight torpedo directional warhead
