采用非线性瞬态动力学分析软件MSC／Dytran，对反舰导弹舱内爆炸冲击波作用于双层舱壁的响应进行数值仿真。此双层舱壁型式为双层夹芯板架结构型式。文中选取3舱室模型作为研究对象，主要改变双层舱壁的夹芯间距、舱壁板和夹芯的厚度、舱壁的材料等参数，分析了双层舱壁各结构参数对双层舱壁抗爆性能的影响，计算了在相同爆炸条件下双层舱壁的结构响应，作为设计新型舱壁结构的参考。在此基础上选取不同的载荷工况对舱室结构进行了数值仿真，得出双层舱壁结构的变形、吸能等响应结果，拟合响应结果，得到了结构的响应预报公式。此响应预报公式可以用于快速估算同种舱室结构在不同工况下的响应。

The numerical simulation on the double bulkhead under cabin explosion shock wave of anti-ship mis-sile is carried out by using nonlinear transient dynamics analysis software MSC/Dytran.The type of double bulk-head is a double reinforced plate frame.We select three-compartment model as an object of study and investigate the anti-explosive performance of the double bulkhead under conditions of different structural parameters.The main changes of the double bulkhead are in sandwich spacing, bulkhead plate thickness, sandwich thickness, and bulkhead materials.Structural response in the double bulkhead is calculated under the same conditions of explosion and simulation of structure carried out under different amount of explosives and different explosion dis-tance.The ship double bulkhead′s responses,including energy absorption and deformation, are presented.Struc-tural response prediction formula is obtained by regression analysis.This response prediction formula can quickly estimate the response of similar cabin structures.
