为研究紧凑型聚能装药结构对侵彻体成型的影响,运用ANSYS/LS-DYNA有限元软件,对不同结构参数药型罩的射流成型进行数值分析。结果表明:当药型罩高小于30 mm,不同装药结构均形成具有一定速度梯度的聚能侵彻体,球缺型罩装药形成的侵彻体尾部杵体小、质量分布均匀、能量利用率高,性能更好;当罩高大于40 mm,不同药型罩装药形成长径比较大的射流,锥形罩形成的射流杵体小、连续性好、能量利用率高,性能更好。 In order to study the influence of the compact charged charge structure on the penetration, the numerical simulation of the jet forming of the different types of coating was carried out by ANSYS / LS-DYNA finite element software. The results show that when the medicine cover is less than 30 mm in height, the charge penetration structures with a certain speed gradient are formed in different charge structures. High utilization rate and better performance. When the cover height is more than 40 mm, the jets with different drug types form a jet with a large aspect ratio, the jets formed by the cone cover are small, have good continuity, high energy utilization, more performance it is good.
