| 摘 要： | 针对2种不同强力甲板结构形式的舰船,应用ABAQUS非线性有限元分析工具,计算舰体在强力甲板大变形损伤状态下的总纵极限承载能力.采用冲击动载荷来模拟得到结构的大变形损伤状态,并将其作为初始状态进行极限承载能力分析.分析结果表明,纵向箱形梁这种新型强力甲板结构形式相比常规强力甲板结构形式,在大变形损伤下舰体总纵极限承载能力等方面具有显著的优越性.

| Abstract: | A study on the longitudinal ultimate strength of warship with different types of strength deck under large deformation damage condition is presented in this paper,using ABAQUS nonlinear FEM tools.An impact load is applied to obtain the large deformation damage conditions,which work as the initial conditions in the ultimate strength analysis process.The result shows that,compared with general type of strength deck,strength deck stiffened by box girders has much better performance on longitudinal ultimate str... |
