The Study Of A Ship Structure Subjected To Underwater Contact Explosion

The ship structure are composed greatly many by the board, girder and so on the basic component. The ships can receive the weapon attack from air and under-water, the ships broadside underwater structure is main part that suffers weapon attack the and so on the torpedo, sea mine. Studies the dynamic response course of ship underwater structure under the contact explosion load function, it has the vital significance regarding the underwater structure under the contact explosion impact load function destruction effect. Because the funds of simulating the experimental of underwater explosion needs is extremely expensive, therefore the domestic and foreign mainly uses the numerical experiment to this question research at present, namely the simulation method .Simulated the typical ships broadside protection structure under the underwater contact explosion load by non-linear dynamical finite element software LS-DYNA. Through compared the ships broadside protection structure the liquid-cabin when the different compartment position and the different quantity 8 kind of cases, researched protection structure various parameters change tendency, obtained the reasonable protection structural style, thus provided for the ships secure protection design reliably foundation...
