Research on shock resistance of modularization cabin

Underwater explosion impulsive loading would not only cause serious damage to ship structure, but also influence the shock resistance of cabin structure. In this paper, based on Duha Man integral theory, the idea of cabin structure about isolation vibration based on modularization design was presented, which can improve the shock resistance of existing cabins. The shock resistance analysis of the modularization cabin about connection pattern by bolt, single-layer, double-layer and floating raft system of vibration isolation is carried out. The results showed that the shock resistance of bolt is the worst and floating raft is relatively superior above all.
