Abstract:

钢板被广泛用于构建防护结构,大量文献报道了单层金属靶的防护性能,而对双层金属靶,特别是大间隙双层金属靶,报道的却很少。在轻气炮上进行了平头杆弹体正撞击由两层5mm厚A3钢板组成的接触式和具有200mm间隙的间隙式双层靶的实验研究,得到了两种结构的初始-剩余速度曲线。实验表明:(1)两种形式双层靶均发生了充塞剪切;(2)接触式双层靶的弹道极限是5mm单层A3靶的1.92倍;(3)间隙式双层靶的抗侵彻性能具有较大的分散性,通过高速摄像和对回收靶板的分析表明,该分散性产生的原因是,弹体贯穿第一层靶后存在两种典型弹道状态;(4)间隙式双层靶存在两个弹道极限;(5)接触式双层靶的弹道极限接近或者大于间隙式双层靶的弹道极限。使用ABAQUS/EXPLICIT有限元软件进行了相应的数值模拟,得到了与实验一致的现象和结果。
