| 摘 要： | 根据《散货船结构共同规范》（CSR）中疲劳强度评估的要求,使用MSC.Patran/Nastran和中国船级社开发的CSR自动加载程序,对176 000 dwt散货船货舱口角隅处进行疲劳强度分析。建立货舱口角隅处的结构有限元模型并细化网格,进行热点应力分析,根据线性疲劳累计损伤原理,进行了疲劳累计损伤计算,结果表明货舱口角隅处的疲劳强度满足规范要求。

| Abstract: | According to the CSR fatigue strength evaluation requirements,the automatic loaded program developed by MSC.Patran/Nastran and CCS is adopted to analyze the fatigue strength on hatch corner of a 176 000 dwt bulker carrier.Structure FEM model of hatch corner has been built up,with the cell refinement to proceed hot dot stress analysis,and the fatigue accumulation damage has been calculated based on linear fatigue accumulating damage principle.The conclusion indicates that the fatigue strength of hatch corner... |
