摘要:
为了提高聚能射流的侵彻性能,结合超高速射流理论设计了一种截顶M形药型罩,运用有限元分析软件ANSYS/LS-DYNA对该药型罩形成射流的过程和射流侵彻靶板的过程进行数值模拟研究;对该药型罩和锥角药型罩形成射流的性能进行比较,并采用静破甲实验进行验证。结果表明,截顶药型罩顶部在爆轰压力作用下先形成内外环形射流,内外环形射流汇聚后形成二级环形射流,二级环形射流汇聚后形成聚能射流头部;截顶M形药型罩形成的射流,头部速度更高,射流头部速度比锥角药型罩提高4.2%,射流速度梯度变大;截顶M形药型罩形成的射流侵彻深度比锥角药型罩提高36.06%,且侵彻形貌较均匀;数值模拟结果与试验结果误差小于5%,具有良好的一致性。
Abstract:
To improve the penetration performance of shaped jet, an advanced M-shaped truncated-cone liner was proposed on the basis of hyper-velocity jet theory, and numerical simulation were performed by ANSYS/LS-DYNA software to study jet formation and penetration against steel target. The jet performances of the M-shaped liner and cone-shaped liner were compared and vertified by static armor experiment. The results show that upon hyper-pressure detonation front of explosive charge, the M-shaped section of M-shaped truncated-cone liner collapses into inner-and-outer annular jets, and inner-and-outer circular jets converge into secondary annular jets, finally a higher-velocity jet tip is obtained with 4.2% increase on the basis of conventional cone-shaped liner, at the meantime a more robust penetration capability is also achieved with 36.06% increase on the basis of conventional cone-shaped liner, which exhibit excellent agreement between numerical simulation and field test with a desirable deviation of less than 5%.
