摘要
Abstract
[Objective]In order to explore the effects of different stiffening configurations on the bearing ca-pacity and anti-blast performance of double stiffened cylindrical shells,a numerical study is made of the re-sponses of four kinds of double stiffened cylindrical shells under hydrostatic pressure and underwater explo-sion load.[Methods]First,finite element models of stiffened cylindrical shells with different structural forms are established.Next,finite element software ANSYS is used to calculate and analyze the influence of each structural form on the strength,stability and ultimate bearing capacity of the cylindrical shell.Finally,fi-nite element software Abaqus/Explicit is used to calculate and analyze the influence of each structural form on the deformation deflection and plastic strain of the cylindrical shell under explosion load.[Results]Com-pared with a traditional single stiffened cylindrical shell with the same mass,the I-shaped double stiffened cyl-indrical shell has a great advantage in carrying capacity.When the explosion load level is low,the anti-blast performance of a double cylindrical shell with small rib spacing is similar,but decreases when the explosion load level is high.[Conclusion]The reasonable design of double stiffened cylindrical shells can yield better design schemes for bearing capacity and anti-blast performance.关键词
