| 摘 要： | 为了研究具有大开口甲板板架结构的稳定性问题,本文设计了含大开口的甲板板架模型,开展了其轴向受压稳定性实验,并采用非线性有限元软件ABAQUS对该模型的屈曲破坏过程进行了数值仿真计算,试验结果与数值仿真结果吻合较好.在此基础上,分析了导致结构屈曲失效的主要因素,为船舶甲板结构稳定性设计提供了参考依据.

| Abstract: | In order to analysis the stability of deck grillage with open hatch, experimental and numericalanalysis of a double-layer deck grillage with open hatchis carried out.The results of experiment and numerical calculation agree well with each other. Based on the experiment, the major incentive ofthe structural failure has been pointed out, which can provide references for stability design of ship structures. |
