摘　　要：本文主要研究半穿甲战斗部对舰船多层甲板的侵彻毁伤效应,分析战斗部不同着靶姿态下的弹道性能。设计不同战斗部装填比方案,运用LS-DYNA非线性有限元软件,讨论半穿甲战斗部着角、攻角对多层甲板穿透效果和弹道偏转的影响,探究装填比对战斗部侵彻能力的影响,对各方案下由战斗部侵彻引起的毁伤效果进行综合评估。Penetration damage effect of semi armor piercing warhead on multi-layer decks is researched,with analysis of warhead ballistic performance under different target attitudes.Different loading ratio warhead is designed,and the software LS-DYNA is utilized to discuss the influence of landing angle and attack angle of the warhead penetration and ballistic deflection.The influence of loading ratio on warhead penetration is explored,and the damage caused by warhead penetration under each scheme has been comprehensively evaluated.
