摘要
作战舰船必须具备承受反舰武器打击的能力。以GBU-12B/B激光制导炸弹直接命中船体主甲板为研究背景,比较分析舰船在遭受打击前后船体强度的变化,并提出在舰船主甲板下加装箱形抗损结构的方案。通过对甲板破口处进行有限元建模,计算该处的应力。分析箱形抗损结构对提高船体剩余强度的影响。研究结果表明,加装箱形抗损结构能够提高舰船剩余强度,进而提高舰船生命力。
The warships have to take measures against attack grom anti-ship weapons. When either before and after the main deck of ship hull is directly attacked by the laser-guiding bomb GBU-12B/ B, the change of strength is comparatively analyzed, and the concept that the box-girders added under main deck is given to improve the resistance capability of structure damage. The stress on the crevasse of deck struck by the bomb is computed by the finite element model, and analyzing the structure with box-girdersas how it impact the residual strength of ship. The results of analysis shows that the hull structure with the box-girders added under main deck improves the residual strength of ship, resulting to improve ship survivability.
