Abstract:

采用系列弹道实验,研究了双层钢/铝爆炸复合靶在不同形状破片侵彻作用下的毁伤机理和抗侵彻性能。实验采用14.5mm滑膛枪发射直径6mm的钢质球形破片和边长4.2mm的钢质立方体破片。基于实验结果,分析了不同形状破片侵彻下靶板的毁伤机理和破坏模式,讨论了破片形状、动能及靶板厚度分布等因素对复合靶抗侵彻性能的影响。结果表明:在球形破片和立方体破片的侵彻作用下,钢面板发生剪切冲塞破坏,铝背板发生延性扩孔破坏;复合靶板抗立方体破片侵彻性能优于抗球形破片侵彻性能;在球形破片的侵彻作用下,当靶板厚度一定时,复合靶板的抗侵彻性能随钢面板与铝背板厚度比的增大而提高,对于立方体破片则相反。
