摘要: 为提高爆炸成型弹丸对目标的定向毁伤效果,设计了一种基于VESF起爆系统的多爆炸成型弹丸装药结构,采用LS-DYNA软件对VESF起爆系统产生的平面波和起爆方式对多爆炸成型弹丸装药威力的影响进行了仿真计算,并通过靶场实验进行了验证。结果表明:采用VESF起爆系统的多爆炸成型弹丸装药产生的爆炸成型弹丸速度较高,可实现多个爆炸成型弹丸的高定向度飞散,并可引爆长径比很大的炸药装药。Abstract: A kind of charge structure for multiple explosive forming projectile is put forward to improve the directional destruction effect on targets. The plane wave produced by shock initiation and initiation styles effecting on damage ability are simulated by LS-DYNA and tested. Results show that MEFP charge with VESF initiation has many advantages, such as higher velocity EFP, higher directionality and being easy to initiate charges of large ratio of height to diameter.
