摘要
为了研究炸高对射流空气及水中侵彻深度的影响,利用AUTODYN软件数值模拟了钨铜合金射流在空气及水中对钢板的侵彻深度.研究结果表明,无论空气还是水中侵彻,都存在一个最佳炸高;当炸高小于4倍装药直径时,水中侵彻深度大于空气中情形;水介质在一定程度上起着炸高的作用,同时对射流头部又产生侵蚀效果.
To study the effect of standoff on the penetration of the shaped charges in the air and water,this paper calculates the penetration into steel of WCu-pseudo-alloy shaped charges in the air and compares to those in the water using AUTODYN software.Numerical results show that there exists an optimum standoff for penetration both in the air and the water.The penetration in the water was even larger than that in the air when the standoff was less than four times charge diameter.Water acts as the standoff to some extent;in the meanwhile,it will shorten the jets by eroding the jet tip.
