| 摘 要： | 针对集装箱船舱口角隅处的应力计算,提出一种针对舱口角隅处网格的自动有限元精细划分算法。在进行完整船有限元分析后,截取出局部舱口角隅模型进行网格细化,将粗网格计算结果作为细网格模型边界条件,再次进行有限元分析。结果表明细化网格分析能反映出应力梯度比较大的区域的应力变化情况,其分析结果好于整体分析结果。 |

| Abstract: | The hatch corner of containership is the region of stress concentrated,it is an effective way that finite element model of the hatch corner intercepted from the whole ship is refined and analyzed again.An automatic mesh refining algorithms for hatch corner was presented.Results show that the refining mesh analysis can reflect the stress change in the region with larger gradient of stress variation,thus the analysis result is better than the one obtained from global analysis. |
| Keywords: | transition element sparse mesh refined mesh stiffness matrix hatch corner |
