摘要
[目的]旨在研究活性破片侵爆作用与惰性破片侵彻作用下 10 mm厚高强度船用钢的失效机制及其防护性能的差异.[方法]采用 12.7 mm弹道枪加载圆柱形破片高速撞击船用钢靶板试验方法,将两种密度相近且质量相同的活性复合破片、惰性钢质破片分别与高强度船用钢板的弹靶作用,分析其作用情况.主要包括破片损伤机制、靶板失效模式及能量释放与吸收特性,得到船用钢靶板在不同破片毁伤作用下的海军标准弹道极限V50.[结果]结果表明:高强度船用钢抗惰性破片与活性破片的弹道极限V50 分别为807 和874 m/s,活性破片穿透能力低于惰性破片,但扩孔能力高于惰性破片,活性破片冲击过程伴随有强烈的火光覆盖,其侵爆毁伤能量整体高于惰性破片单一侵彻动能.[结论]试验研究结果能够为舰船防护结构设计与活性毁伤技术应用提供一定的数据支撑与指导.
Abstract
[Objectives]This paper investigates the failure mechanism and protective performance differ-ences of 10 mm thick high-strength ship steel when it is subjected to penetration-deflagration by reactive and inert fragments respectively.[Methods]A 12.7 mm caliber ballistic gun is used to shoot cylindrical frag-ments at high-strength ship steel.Reactive composite fragments and inert steel fragments with a similar dens-ity and quality interact with the high-strength steel target.The fragment damage mechanisms,target failure modes and energy absorption and release characteristics are then compared,and naval standard ballistic limits V50 for the ship steel target are obtained under different fragment damage conditions.[Results]The ballist-ic limits V50 of the ship steel target against inert and reactive fragments are 807 m/s and 874 m/s respectively.The perforation ability under reactive fragments is superior to that under inert fragments,but its expansion ability under reactive fragments is inferior to that under inert fragments.The impact process of reactive frag-ments is accompanied by strong firelight coverage,and their total penetration-deflagration energy is higher than the single penetration kinetic energy of inert fragments.[Conclusion]The experimental results of this study can provide data support and guidance for the design of ship protective structures and the application of active damage technology.
