| 摘 要： | 随着现代战场的变化,根据混凝土毁伤目标的需要,提出了一种新型并联装药结构,其侵彻体冲击钢筋混凝土目标时既要有较高的穿深力,又要有足够大的穿孔直径,使两者兼顾,才能为后级随进弹创造条件.结合杆式射流的特点提出了一种新型并联装药结构,并用有限元LS-DYNA软件对杆式射流侵彻混凝土的过程进行了数值模拟.结果表明这种并联杆式... |

| Abstract: | With modern battlefield changing,the According to the need of damaging concrete target,Integrated the trait rod-shaped,a new parallel structure of pre-charge level is proposed,the pengtrator is required to be with not only high penetration depth but also large borehole diameter.a numerical simulation analysis for the rod-jet formation process of parallel structure of pre-charge are performed.The results show that the parallel shaped charge configuaration of the target is much larger than the single jet stru... |
