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.
