摘　　要：普通的船舶一般为单壳或双层壳,它们之间用普通肋骨连接.Y型舷侧结构是指船体舷侧在物理模型上的双壳之间用横向Y字型板代替部分肋骨,借此提高舰船结构抗冲击性能.该文针对以上情况,通过大型有限元分析软件ANSYS/LS-DYNA并配合大型的有限元计算软件ABAQUS进行数值实验,对Y型舷侧结构在遭受武器攻击后的承受能力进行研究.数值仿真实验分析表明:若船体舷侧采取适当的Y型结构形式,可以大大降低水下爆炸所造成的结构损伤和破坏,从而进一步提高舰船的生命力.The shipboard structures of general watercrafts, which are connected by common ribbings, are usually either single or double hull. Y model shipboard structure implies that using Y type board to substitute some of those ribbings between the double hulls of shipboard on physical ship models, and improve counter-impingement capability of shipboard structure. Aiming at the above case and trying to figure out a brand new way of thinking and research method, this paper analyzed the numerical experiment,of which the values are acquired through limited variable large finite element analysis software ANSYS/LS--DY- NA, together with limited variable calculating software ABAQUS,and emphasized the durability of Y type shipboard under the weapon assault. The analysis of numerical simulation indicates that the adoption of proper Y-shape shipboard structure can tremendously reduce the structure damage and scathe by underwater explosion so as to further improve the vitality of warships.
