摘要基于ABAQUS软件中的耦合欧拉-拉格朗日（CEL）算法，模拟近场水下爆炸气泡射流载荷对船体外板的冲击过程，首先将CEL算法的数值结果与Obara试验结果进行对比，验证数值方法的有效性。在此基础上对水下爆炸射流的载荷压力特性、射流的速度分布特性及射流引起的结构剪应力分布特性进行研究，旨在为实际海战中船体外板遭受水下爆炸射流载荷的抗冲击设计提供一定参考。

Abstract：Based on the coupled Euler-Lagrange (CEL) algorithm in the software ABAQUS, processes of near field underwater explosion bubble jet load impacting hull plates were simulated. The numerical results of CEL algorithm agreed well with Obara’ test ones, so the effectiveness of the numerical method was verified. Then, the load pressure characteristics of underwater explosion jet, jet velocity distribution features and the distribution features of structural shear stress induced by jet were investigated. The results provided a reference for the anti-impact design of hull plates against underwater explosion jet load in practical sea-battles.

Key words： underwater explosion jet load hull plate dynamic response analysis
