摘　　要：基于通用仿真软件,对某油船进行了远场水下爆炸的动响应分析。研究了药包沿船长方向分布、沿水深分布和不同攻角对船体结构的影响。可以看出,中远场水下爆炸对油船的冲击响应,主要表现为总体响应,局部效应并不明显;爆距对冲击响应有很大的影响,而在远场爆炸时攻角对其影响不明显,随着爆距的增加,船体结构响应逐渐减小;武器的毁伤效应对船体外板影响最为显著,随着能量在船体内的传播,到主甲板时迅速衰减。通过进行计算分析得出了一些结论,为油船的设计及建造提供参考。Based on a common software,this paper studies and analyzes the oil tanker dynamic response of far-field underwater explosion and shock responses of ship structure about TNT distribution along length,depth and attack angle. Research results show that overall shock response is main for tanker in the Far-field explosion,while the local effect is not obvious;explosive distances has more effect on shock response than attack angle,when the explosive distances increases, the shock response is decreasing. In the shock, damage effects on hull plate significantly, but shock response of main deck attenuates due to energy transmission in hull. This conclusions presented will provide some references for tanker design and construction.
