摘　　要：为提高舰艇舱室及内部设备的抗爆炸冲击能力,应用瞬态分析软件LS-DYNA分析计算包含大型设备的舰艇舱室内部爆炸冲击响应情况。使用弹塑性金属材料本构模型及JWL炸药本构模型建立舱室有限元模型后,使用流固耦合算法首先对舱室内爆炸冲击波的传播情况进行计算分析,然后通过设备基座变形和设备基座冲击加速度2个方面对舱室内设备爆炸冲击响应情况进行比较分析,评估舱壁厚度对设备冲击的影响情况。最后得出相关结论,这些结论对舱室内设备的合理布置以及设备抗冲击结构设计有一定的参考价值。For improving anti-explosive ability of ship cabin structure and inner equipment, the shock response of ship cabin include equipment were analyzed in inner explosion condition by explicit code LS-DYNA. The cabin FE model was created by elastic-plastic mental material and JWL explosive constitutive equation. Then the shockwave transmission of single cabin explosion was calculated based on fluid-solid couple algorithm. The shock response of cabin equipment was analyzed through equipment base deforming and base shock acceleration. And influence of cabin wall thickness to equipment shock response was evaluated based on above calculating results. At last, some conclusions were put forward. These conclusions can offer some reference for improving anti-explosion ability of cabin equipment and arranging equipment reasonably in cabin.
