药型罩锥角对聚能杆式侵彻体影响的数值分析

为研究药型罩锥角对聚能杆式侵彻体的影响，运用AUTODYN 软件建立聚能装药模型，对90?～130?大 锥角药型罩形成的聚能杆式侵彻体进行数值模拟。建立装药结构有限元模型，研究不同锥角药型罩形成的聚能杆式 侵彻体在同一时刻、同一炸高下的成型情况，分析在5 倍装药口径炸高条件下聚能杆式侵彻体对均质靶板的侵彻情 况，得到在装药口径和高度一定的前提条件下，药型罩锥角对聚能杆式侵彻体成型参数的影响规律。研究结果表明： 药性罩锥角在100?～110?时，形成的聚能杆式侵彻体具有较好的连续性、稳定性与侵彻性能，可为聚能杆式侵彻体 战斗部的设计及应用提供参考。

Numerical Analysis on Effect of Jetting Projectile Charge by Liner Cone Angle

In order to study the effect of cone angle of the liner on jetting projectile charge (JPC), AUTODYN simulation software is used to build the shaped charge model. Numerical simulation of the jetting projectile charge with the large angle between 90?-130? of the liner is performed. The jetting projectile charge molding with different liner angle at the same time and the same burst height is studied, and the penetration of the homogeneous target is analyzed under the condition that the burst height is 5 times of the charge diameter. Under the same diameter and height of shaped charge, the effect laws of cone angle of the liner on the jetting projectile charge molding parameters are proposed. The research also shows that the jetting projectile charge has better continuity, stability and penetration performance when the liner angle is 100?-110?. The results provide a reference for design and application of jetting projectile charge warhead.
