摘要
药型罩的加工精度是影响破甲战斗部破甲深度的一个重要因素。通过理论分析,研究了药型罩加工精度对射流性能的影响,同时利用ANSYS/LS_DYNA软件建立了具有不同加工误差的药型罩及相应的战斗部模型,并进行了一系列的数值模拟。结果表明,药型罩加工误差的存在会影响射流性能,而且破甲威力随着药型罩加工误差的增大而下降,为研究破甲战斗部破甲深度问题提供参考。
The precision of Liner is a major factor impacting the depth of penetration of armor-penetrating warhead. By theoretical analysis, the precision of Liner＇ s impact on jet performance was research,and the ANSYS/LS_DYNA software was used to build liner＇ s model with different machining error in the same time. By a series of numerical simulations,the results show that the existence of liner processing error would impact the jet performance,and with liner＇ s processing error increasing, the penetration power declines, providing reference for the penetration depth problem of armor-penetrating warhead.
