| Abstract: | Based on the energy-absorbing theory, four new kinds of anti-explosion ship structural forms of double bottoms are proposed. The FEM models of a traditional form and four new structural forms are established. Numerical simulations are done by the software MSC.Dytran. The energy-absorbing properties, the maximum deformation of inner-bottom plate and the acceleration of typical position of the five kinds of structural forms are obtained under the same underwater explosion load and the anti-explosion properties of the five kinds of structural forms are compared and analyzed. From them, a better structural form is obtained. |
