空爆载荷作用下舰船结构总强度分析

Total strength analysis of warship structure under air explosive load

空中爆炸对舰船结构总强度的影响一直是业内研究的重点问题之一。本文经过广泛调研选取典型武器和典型结构,应用有限元软件对炸药、流场及舰船结构进行实体建模。采用通用有限元计算软件LS-DYNA对某典型舰船结构在空中爆炸载荷作用下的毁伤效果进行分析,着重研究舰船结构总强度在典型攻击武器打击下的毁伤程度,并利用已有的成熟的评估理论,对其最终的毁伤效果进行分析和评估,得出一般性的结论,为舰船的结构设计提供参考。

The strength of warship struture under air explosive load is one of important problems in the national defence field. In this paper typical weapons and structure is obtained and the element model is estabileshed and the damage of the warship structure subjected to air explosive is analysed and the total strength is researched and estimated based on evaluation theory and the general conclusion can be drawn and the results could be reference in majorization design.
