摘　　要：为了探讨钨合金破片对Q235钢靶的侵彻效应,本文研究了在一定弹靶系统下,破片穿靶所需能量随破片入靶速度的变化关系。采用AUTODYN有限元分析软件数值模拟了钨合金球形破片侵彻钢板,得到穿靶能量随破片速度的变化规律,同时获得了钨合金球形破片侵彻钢板的开坑直径随破片速度的变化规律。在此基础上,通过使用量纲分析的方法,获得了球形破片侵彻靶板的入靶速度与穿靶能量的关系式,并用不同速度的破片进行穿靶试验。研究表明:随侵彻速度的增大,穿靶所需能量增大,且获得的试验值与计算值具有较好的一致性,研究结果具有一定的应用价值。The relationship between the energy required for the fragment to penetrate the target and the fragment speed was studied under certain projectile target systems to investigate the penetration effect of tungsten alloy fragments on Q235 steel targets.First,the AUTODYN finite element analysis software was used to simulate the penetration of tungsten alloy spherical fragments into the steel plate,obtaining the variation law of the penetration energy and the fragment speed.Meanwhile,the variation law of the crater diameter and the fragment speed was also obtained.On this basis,the formula for the relationship between the penetration speed and the energy required for the fragment to penetrate the target plate was obtained using the dimensional analysis method.Target penetration tests were conducted with fragments at different speeds.The results show that the penetration energy increases with penetration speed,and the obtained test value is in good agreement with the calculated value;hence,the results demonstrate a certain application value.
