| 摘 要： | 基于散货船共同结构规范（CSRBC）的热点应力法，对一艘30000t级散货船内底板与底凳的斜板相交处进行了疲劳强度分析。通过对疲劳热点位置建立精细网格模型，采用中国船级社开发的软件CCS-Tools及英国劳氏船级社开发的SHIPRIGHT进行了热点应力分析及疲劳寿命计算。另外，还介绍了采用电子表格计算疲劳寿命的方法。

| Abstract: | The fatigue strength analysis of the connection between the inner bottom plate and the sloping plate of the lower stool of a 30 000 dwt bulk carrier is carried out, based on the hot spot stress method in Common Structure Rules for Bulk Carders. The hot spot stresses at the locations are calculated on the basis of a very fine finite element model and CCS-Tools and SHIPRIGHT are adopted in the fatigue assessment. The method of checking fatigue life by Excel is introduced. |
