为了研究攻角对两级穿爆战斗部侵彻水面舰艇目标性能的影响,利用LS-DYNA有限元软件进行了两级穿爆战斗部侵彻双层等效靶板的数值模拟,分析攻角对前、后级战斗部剩余速度、壳体强度、速度偏角以及前、后级战斗部之间行程差的影响。小攻角对于前级战斗部侵彻性能的影响不大,对后级战斗部的强度有较大影响;攻角增大,后级战斗部的变形和破坏加剧;攻角有利于前、后级战斗部之间行程差的增大。研究结果为新型战斗部的设计提供了参考。

In order to study the influence of the Piercing-Blasting warhead penetrating surface vessel target with attack angle, used finite software LS-DYNA to simulate the process of the two-stage piercing-blasting warhead attacking double equivalence target, analyzed the influence of residual velocity, shell strength, speed declination and stroke different of the two stage warhead at attack angles. The results show that when the attack angle increase, it has little affect to the penetration of pre-stage, but the last stage warhead facing austere influence; When attack angle increase, the deformation of last stage warhead aggravate; The attack angle is beneficial to increase the stroke different between the pre-stage and last stage warhead. The results can provide reference for new warhead design.
