| 摘 要： | 采用数值模拟方法,并结合试验分析对侵爆战斗部作用下的机场跑道毁伤效应进行研究,重点分析了炸点深度对侵爆战斗部作用下的机场跑道毁伤效应的影响。采用Lagrange算法与SPH算法转换可以实现侵彻效应和爆炸效应连续计算。研究表明:炸点深度对反跑道毁伤效果影响显著;炸坑面积随着炸点深度变化呈二次曲线变化;在弹靶确定条件下存在一最佳炸深,并可以通过本文方法得到。采用计算跑道各层吸收爆炸能量多少的方法可以对反跑道侵爆战斗部的毁伤效应进行机理分析。

| Abstract: | The damage effects of runway subjected to the penetrating-exploding tandem submunition were studied by using the numerical simulation assisted with experiment analysis.It focuses on the influence of the blast depth on the damage effects.The penetration and explosion effects can be continuously simulated by using Lagrangian and SPH algorithms.The simulated results show that the blast depth greatly influences the damage effects of anti-runway submunition;the crater area changes with the blast depth in a parab... |
