摘　　要：为了给侵彻爆破弹引信自调延期机构设计提供参考,解决目前设计过程缺少经验公式计算的现状,提出了弹丸正侵彻有限厚混凝土靶过程最大前冲过载经验公式。采用ANSYS/LS-DYNA有限元软件数值模拟了125mm口径侵彻爆破弹正侵彻有限厚C35混凝土靶过程,分析了弹底引信前冲加速度变化规律,借鉴弹丸冲塞侵彻钢靶的分析方法,根据不同侵彻工况下的仿真数据,拟合得到了弹丸正侵彻有限厚C35混凝土靶过程最大前冲过载经验公式,分析表明该经验公式初步可行。In order to provide reference for the fuze set forward overload during projectile penetration of limited thick concrete target and provide reference for adjusting extension mechanism design,the simulation of projectile penetration of limited thick concrete target was carried out with ANSYS/LSDYNA.The set forward acceleration of the base fuze was analyzed.Draw lessons from the analysis method of projectile penetration steel target,the empirical formula of the biggest set forward overload during the projectile penetration C35limited thick concrete target was fitted according to the simulation dates.The empirical formula could provide reference for fuze adjusting extension mechanism design.
