为研究橡胶复合靶抗破片侵彻过程及能量变化规律,利用AUTODYN-3D有限元分析软件获得20种靶板抗破片模拟弹(FSP)侵彻的弹道极限和极限侵深,通过分析仿真结果研究了FSP弹丸以多种着靶姿态侵彻不同厚度靶板的穿甲过程,同时进一步研究橡胶夹层厚度和FSP弹丸着靶姿态对破片临界贯穿条件下靶板能量变化和各部分吸能比率的影响。结果表明:破片着靶姿态固定,夹层厚为10 mm时夹层板吸能比率最低;夹层厚度固定,破片着靶角为45°时夹层板吸能比率最高。
In order to study the process and energy variation of anti-fragment penetration of rubber composite targets, ballistic limit and limit invasion of 20 target anti-fragment projectile (FSP) penetrations were obtained by using AUTODYN-3D finite element analysis software. By analyzing the simulation results The penetration process of FSP projectile penetrating different thickness target plates with various targets was studied. The influence of the thickness of rubber interlayer and target attitude of FSP projectile on the energy change of target plate and the energy absorption ratio of each part were also studied. . The results show that the sandwich plate has the lowest energy absorption rate when the thickness of the sandwich plate is 10 mm. The sandwich plate has the highest energy absorption rate when the sandwich thickness is fixed and the target angle is 45 °.
