破片对充压壳体的毁伤特性研究

Damage Characteristic Research on the Fragment Penetration into Pressurized Shell

为了得到充压壳体在破片作用下的毁伤特性,利用LS-DYNA软件,针对充压壳体在破片作用下的毁伤模式与毁伤机理进行了分析。研究了在壳体内压不变情况下,破片大小、破片形状以及交会状态等因素对壳体毁伤程度的影响。获得了不同条件下的壳体毁伤特性和毁伤规律,以及破片大小、破片形状和交会状态的选取标准,所得到的结果可为反导战斗部的结构设计及引战配合提供技术支撑。

In order to obtain the damage characteristics of pressurized shell under the action of fragments,the damage pattern and damage mechanism were analyzed by using the LS-DYNA software. Investigate the fragment size,fragment shape and the intersection of state and other factors on the extent of shell damage under the situation that the internal pressure of the shell is a constant. The damage characteristics and damage law under different conditions,and the selection criteria of fragment size,shape and the intersection of state have been obtained. The results can provide technical supports for the anti-missile warhead design and the coordination of fuze and warhead.
