摘要
利用有限元仿真程序,分析了反舰导弹侵彻舰船过程中的结构变化和过载响应,获得了战斗部侵入舱体后的位置信息,据此确定出弹靶舱室内爆的初始条件,开展了模拟舱室抗装药内爆的结构设计和静爆试验。研究结果表明:反舰导弹能够穿透高强度钢制舷体,在目标内实现内爆效应;模拟舱室在内爆情况下发生因焊接缝裂开致结构垮塌;加厚壁结构弯曲变形吸收冲击波能,局部凹陷,整体无破坏,能够起到防护重要舱室的作用。
With help of finite element program,the ship's structural changing and overloading response were analyzed in process of a missile pentrating to a ship.The position information of the warhead of the missile in the cabin of the ship was obtained,it gave rise to the initial condition of the ship's inner explosion.Then,the cabin model was designed and its inner-explosion tests were conducted.The study results showed that the anti-warship-missile penetrates the shipboard,making large overload to fuse and realizing inner-explosion;the cabin structure is collapsed when it faces high detonation wave;owing to weak strength of welding positions,the high pressure leaks from there;due to good absorption of shock wave energy,thick board is not broken but cupped partially;thick board can prevent the vital cabin from damaged even though the ship suffers from inner explosion.
