V型夹层炸药干扰杆式侵彻体的影响因素研究

Study on Influence Factors of V-shaped Sandwich Explosive Disturbing Rod Penetrator

为提高爆炸式反应装甲对杆式侵彻体的防护能力,加强对V型夹层炸药干扰杆式侵彻体的研究,利用数值模拟软件LS-DYNA分析入射角θ、两平板炸药间距离H1、V型夹层炸药距主装甲距离H2等因素对V型夹层炸药干扰杆式侵彻体的影响。结果表明,随着θ增加,V型夹层炸药的干扰作用不断加强,并且当θ=60°时,干扰作用突然跃升;随着H1增加,干扰作用先加强,然后又下降;随着H2增加,干扰作用先保持不变,然后稍微加强,之后又保持不变。

For improving the defensive capacity of explosive reactive armor for rod penetrator and promoting the study of V-shaped sandwich disturbing rod penetrator, the impact of the angle /9, the distance between two sandwich explosive H1 and the distance between V-shaped sandwich explosive and main armor H2on V-shaped sandwich explosive disturbing rod penetrator were analyzed by using numerical simula- tion software LS-DYNA . The results showed the impact of V-shaped sandwich disturbing rod penetrator became greater ad the 0 increased and the impact jumped suddenly when θ= 60° ;with the increase of H~ ,the impact increased firstly, and then decreased ; with the increase of H2.the impact remained unchanged firstly, then increased slightly, and after that remained unchanged once again.
