摘要
针对引信传爆管输出飞片远距离引爆弹丸主装药优化设计问题,应用ANSYS/LS-DYNA软件研究了12种飞片起爆方案,模拟出炸药驱动飞片起爆过程,并得出不同形状、不同厚度飞片冲击起爆炸药时炸药端面爆轰压力与时间的曲线。结果表明:在飞片厚度设计经验范围内,平板型飞片冲击炸药的爆轰压力随飞片厚度增加而增大;碟型飞片冲击炸药的爆轰压力随飞片厚度增加而减小;锥型飞片越厚越不易引爆炸药,而球缺型飞片越薄越不易引爆炸药,并且对飞片厚度极为敏感。
In order to solve the problem for optimization design of flyer from fuse booster initiating main charge of projectile in remote distance, twelve groups of flyer initiation schemes were simulated and researched with ANSYS /LS-DYNA software, modeling the entire initiating process of explosive driving flyer and obtaining the detonation pressure and time curve with the different shapes, different thickness flyers impacting explosive. The results show that, in flyer thickness empirical design range, the detonation pressure increases for plate flyer impacting explosive with flyer thickness increasing, but it decreases for saucer flyer; it is not easier to detonate explosive with cone flyer get thicker, and with ball-gap flyer get thinner, ball-gap flyer is very sensitive to flyer thickness.
