| 摘 要： | 以德国F124护卫舰纵向箱型梁甲板结构型式的舱段为研究对象,采用流固耦合方法计算其在空爆作用下的甲板变形。采用阻尼因子法,对各冲击因子下箱型梁和普通甲板结构型式舱段塑性变形后的极限承载能力进行比较分析。研究结果表明:在遭受非接触爆炸冲击后,箱型梁甲板结构型式与普通甲板结构型式相比,具有变形小、变形后舰体极限承载能力下降低等优势,因而能够显著提高舰船生命力。

| Abstract: | Utilizing the longitudinal box girder deck structure of Germany F124 frigate as a study case,the strength deck deformations under non-contact explosion were calculated by the fluid-structure coupling method.Ultimate bearing capacities of box girder and ordinary warship compartment structure with plastic deformation damage under various impact factors were compared and analyzed by the damping factor method.The results indicate that under non-contact explosion,compared with ordinary deck structure,box girder ... |
