摘要
采用静爆实验和理论分析相结合的方法,对活性射流作用钢靶侵彻爆炸联合毁伤效应进行了研究.实验结果表明,与金属射流相比,侵彻深度显著减小,但活性射流侵彻钢靶形成的侵孔直径更大,并伴随有更强的爆裂毁伤效应.基于金属射流准定常破甲理论和伯努利修正方程,引入活性材料弛豫时间参数,建立了活性射流作用钢靶侵爆毁伤效应分析模型,从机理上解释了活性射流对钢靶的毁伤行为及效应.
The damage effects of reactive material jet against steel targets were researched by the combination of static explosive experiments and theoretical analysis.The experimental results show that,compared with the traditional metal jet,the diameter of the penetration hole formed by reactive material jet in steel targets was much larger together with stronger blast-induced crack effects,while the penetration depth shows a significant decrease.Based on the quasi-steady incompressible fluid theory and modified Bernoulli equation,a theoretical model for analyzing the penetration and blast combined damage effects was developed to consider the self-delay imitation time of reactive material jet.As such,a theoretical explanation from the perspective of damage mechanism about the combined damage effects was presented by this analytical model.
