摘　　要：鱼雷作为水中主要兵器之一,在现代海战中发挥着重要作用。研究鱼雷壳体在水下爆炸载荷作用下的动响应已经成为国内外研究学者的重要课题。在进行数值仿真计算时,很少有学者考虑鱼雷舱段间的楔环连接结构,该结构对鱼雷的动态响应有重要影响。本文利用有限元分析软件Abaqus,采用数值仿真的方法研究带有楔环结构的某轻型鱼雷在水下爆炸载荷作用下的动态响应。通过用体单元建立的模型与利用壳体单元建立的模型进行比较,并考虑多种工况下的等效塑性应变PEEQ,以及改变爆心位置对鱼雷动态响应的影响,得出鱼雷动态响应的一些规律。该研究旨在为轻型鱼雷结构的设计和优化提供参考。As a main kind of underwater weapons,torpedoes play an important role in modern sea combat.The study of dynamic response of torpedoes subjected to underwater explosion loadings has been an important task for researchers around the world.When performing numerical computations and simulation,however,few studies have considered wedge-ring joint structures between cabins,which have a huge influence on dynamic response of torpedoes subjected to underwater explosion.Adopting numerical computation method,this work addresses dynamic response of a lightweight torpedo with wedge-ring joint structures subjected to underwater explosion using non-linear finite element software ABAQUS.Comparing the model established by volume element type with the model which was made by shell element type,this study considers equivalent plastic strain PEEQ in many conditions and impacts on dynamic response of the torpedo by changing detonate position.We can conclude a series of laws from the results.The research aims at providing reference to design and optimize torpedo structures.
