【摘要】 本论文采用试验得到数据,通过计算分析,进行了增益破片战斗部在不对称起爆状况下对比中心起爆情况下战斗部的破片飞离速度、破片密度场分布及破片增益情况研究。试验和分析结果表明：不对称起爆在沿目标方向对破片飞散有一定的聚汇作用,效果较不明显。破片飞离速度在不对称起爆条件下受影响较大,在半周方位角之内,破片飞离速度依照方位角度的递增加而递变增大。一个起爆点不对称起爆优于点中心对称起爆,与中心对称起爆相比,在目标方向上一个起爆点不对称起爆的破片飞离速度有着特别大的增加现象,最大增益值约为11%。通过本文的试验分析总结,理论研究推导得出了破片增益战斗部的增益情况的论述,本文分析论述的结论能够为战斗部工程设计提供借鉴和参考。更多还原

【Abstract】 The paper uses the method of test and numerical simulation combining to study the fragmentation speed, density distribute of directed warhead under eccentric initiation condition and their gain comparing with the centre initiation mode. The study results shows:the eccentric initiation has some convergence function on fragmentation, but isn’t very obvious at the target direction. It is very outstanding influence on fragmentation speed. The fragmentation muzzle speed increases with azimuth between a harf circle azimuth. A end eccentric point initiation will be better than the centre initiation. The fragmentation speed at target direction has obvious increase than one under centre initiation condition. The maximum value of gain is about 11%. The gain of the directed warhead under the eccentric initiation condition is obtained through the article’s study. The results will provide the beneficial reference for warhead engineering design.更多还原
