摘要
为研究弹药破片效应对目标装甲的毁伤效能,对预制破片战斗部爆炸后的破片场速度分布进行了有限元仿真,并进行后处理得到钨柱预制破片在爆轰作用下的飞散情况以及速度变化曲线,随后利用有限元分析软件LS-DYNA进行破片对靶板的侵彻过程仿真,得到破片对靶板的极限穿透速度,并设计试验进行了验证,试验结果表明该仿真方法的可行性。
In order to research the damage effectiveness of the warhead fragmentations effect on the armor of target,the velocity of the warhead fragmentations field after explosion is simulated by finite element,and then post-processing is performed to obtain the situation of fragments distribution and the speed curve of the prefabricated tungsten-column fragmentations produced by the detonation.Then,the finite element analysis software LS-DYNA is used to simulate the penetration process of the fragmentations on the target plate,and the limit penetration velocity is obtained,and the designed experiment is performed to verify the feasibility of the simulation method.
