摘　　要：以吸能原理为理论依据,提出船舶双层底的四种新型抗爆结构形式,建立传统形式和四种新型结构形式的有限元模型.利用MSC.Dytran软件进行数值仿真,获得在相同水下爆炸载荷下五种结构形式的吸能性能、内底板最大变形量、典型部位加速度,并分析比较了五种结构的抗爆性能,从中获得较优的结构形式.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 A^SC.Dytran. The energy-absorbing properties, the maximum deformation of inner-bottom plate and the acceleration of Opical 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.
