摘要
为获得侵爆战斗部对机场跑道的毁伤效应,采用数值模拟方法及试验方法研究了装药量及炸点深度与炸坑面积的关系.采用Lagrange算法与SPH算法转换可以实现连续计算侵爆战斗部的侵彻效应和爆炸效应;通过数值模拟、试验分析及线性回归方法得到装药量、炸点深度与炸坑面积之间的关系式.结果表明,装药量对机场跑道毁伤效果的影响显著,装药量与炸坑面积成线性关系.
To study the damage effect of penetration-explosion warhead on runway,the relation between crater area to charge weight and blast depth was studied by numerical method and experiment.The effects of penetration and explosion for warhead can be simulated by Lagrange and SPH arithmetic respectively and continuously.By simulation,experimental analysis and linear regressiveness,the equation of charge weight,blast depth and crater area was obtained.The influence of charge weight on damage effect of runway is significant.The crater area is linearly related to charge weight.
