| 摘 要： | 以320000DWT矿砂船NO．1舱口盖为研究对象，使用MSC．Patran软件建立舱口盖结构模型，根据规范IASCUR$21。施加相应的载荷、边界条件等。利用MSC．Nastran软件对该结构进行数值计算，分析结构的应力水平，最后对NO．1舱口盖的屈服和屈曲强度进行校核，经过分析得出NO．1舱口盖的强度满足规范IASCUR$21要求。

| Abstract: | This paper studies the NO.1 hatch cover of a 320 000 DWT ore carriers. The hatch structure is modeled and simulated by using software of MSC.Patran,the corresponding load and boundary conditions are prescribed according to the IASC UR S21specification. The structural stress level of the structure is analyzed,the yield strength and buckling strength of NO.1 hatch cover are verified,which shows that the strength can meet the requirements of IASC UR S21 specification. |
