摘要
基于剩余穿深理论,依据聚能射流对钢靶板侵彻毁伤作用机理,推导出2种等效模型,并结合数值模拟建立了聚能射流侵彻下某舰船装甲钢与603钢靶板的等效关系。结果表明:当舰船钢厚度较小时,舰船钢与603装甲钢的等效厚度比约为1;当舰船钢厚度较大时,两者等效厚度比约为1.13。由此等效关系可给出用于战斗部考核性穿靶试验中相应均质靶板的确定厚度,从而为用603装甲钢靶代替该舰船钢进行聚能射流威力考核试验提供依据,达到了简化、经济、方便、有效的目的。
On the basis of the residual penetration theory,two kinds of equivalent models are derived based on the damage mechanism of shaped charge jet to targets. Combing with numerical simulation,the equivalent relation of ship steel and 603 steel under penetration of shaped charge jet is built. The results indicate that when the thickness of ship steel is small,the equivalent thickness ratio of ship steel and 603 armor steel is about 1;and that when the thickness of ship steel is big,the equivalent thickness ratio...
