抵御小口径火炮弹道侵彻装甲防护模拟实验研究

为研究舰艇结构在小口径火炮弹道冲击下的响应以及各种舰用装甲结构抵御小口径火炮弹道冲击的有效性，以典型的小口径火炮战斗部为模拟对象，根据弹道冲击的相似理论，分别设计了模拟实验的弹体和6种靶板结构，并进行了弹道冲击实验研究。模拟实验结果表明，普通舰艇结构不能抵御小口径火炮弹道侵彻，必须设置专门的防护装甲；采用陶瓷/钢/纤维增强复合材料组合装甲结构抵御小口径火炮时，装甲防护结构比均质钢装甲减轻约60%；陶瓷材料能改变背板的破坏形式和破坏程度，大大增加背板的吸能量，此外，陶瓷对弹体的侵蚀、钝化及碎裂能大大降低弹体的侵彻能力。

Experimental study on armor protection against ballistic impact of small caliber artillery

The response of ship structure and the effectiveness of varying armor structure under ballistic impact of small caliber artillery were studied experimentally.Ballistic impact experiment was carried out to simulate the impact of typical warhead of small caliber artillery.Projectile and 6 kinds of targets were designed according to the similarity theory of ballistic impact.The results show that the structure of ship cannot resist the attack from small caliber artillery,and special armor needs to be equipped.The combining armor of ceramic,steel,fiber reinforced composite can save 60% approximately in weight,compare to steel armor.The use of ceramic can change the failure mode and extent of steel back plate,and greatly improve its energy absorbing.In addition,ceramic can eroding,mushrooming and crash the projectile,those can greatly degrade its penetration performance.
