Optimization research on broadside cabin inside structure of warship underwater defensive structure

WU Lin-jie;ZHU Xi;HOU Hai-liang;CHEN Peng-yu;Dept.of Naval Architecture Engineering,Naval Univ.of Engineering;  
The damage of 3broadside defensive structures subjected to underwater contact explosion is contrastively researched by using the LS_DYNA software,as well as the expansion process of explosion gas inside broadside cabins of defensive structures.The influence of broadside cabin inside structure forms on expansion process of explosion gas inside broadside cabins is mostly analyzed.The research shows that,inside broadside cabin of warship underwater defensive structure,designing separate vertical plates with holes easily conduces to explosion venting and pressure reducing than designing separate vertical plates without holes,and designing "separate vertical plates with holes+ horizontal plates" structure not only conduces to explosion venting and pressure reducing,but also preserve enough statics strength of the broadside cabin.
