摘要:
在保证半球形药型罩开孔大、开孔均匀的优势前提下,为了提升半球形药型罩的侵彻能力,设计了一种新型圆柱-半球结合药型罩;采用数值模拟软件ANSYS/LS-DYNA对半球形药型罩、圆柱-半球结合药型罩聚能侵彻体的成形过程及对45号钢板的侵彻过程进行数值模拟,并分析了两种聚能侵彻体的头尾部速度、拉伸长度等参数以及对45号钢板的侵彻能力。结果表明,在相同装药结构下,与半球形药型罩相比,圆柱-半球形药型罩形成的聚能侵彻体头部速度提升了16.67%;对45号钢板的侵彻能力提升了16.82%,且基本上仍然具有半球形药型罩开孔大且均匀的优势。通过试验验证,数值模拟计算的侵彻深度和表面开孔直径误差分别为3.4%和2.9%,证明了数值模拟结果的准确性。
Abstract:
To improve the penetration ability of hemispheric liner, under the premise of ensuring the advantage of large opening and uniform opening of the hemispheric liner, a new cylinder-hemisphere combination of liner was designed.The numerical simulation of shaped charge penetrator formation in process of cylinder-hemisphere combination of liner and hemispheric liner,and the penetration process of No.45 steel plate was performed by using the numerical simulation software ANSYS/LS-DYNA, and the jet of head and end velocity, stretching length etc. parameters of two shaped charge penetrator and the penetration ability of No.45 steel plate were analyzed. The results show that under the same loading structure, compared with the hemispheric liner, the head speed of shaped penetrator formed by cylinder-hemisphere liner increases by about 16.67% and the penetration capacity of No. 45 steel plate is raised by 16.82%. The deviation of penetration depth and surface opening diameter calculated by numerical simulation is 3.4% and 2.9% respectively, which proves the accuracy of numerical simulation.
