| 摘 要： | 基于谱分析方法对于CTV模型的易疲劳区域进行筛选,对于筛选出的舷侧纵骨切口疲劳热点区域,考虑水线附近的水压力动态折减因素进行单独校核。参考校核结果,优化纵骨切口角隅疲劳热点区域的补板结构形式,使应力平稳过渡,使疲劳寿命满足设计需求。

| Abstract: | The fatigue prone area of CTV model was screened based on spectral analysis method, and the selected fatigue hot spot area of longitudinal incision on the side of the ship was checked separately with the dynamic reduction of water pressure near the waterline considered. According to the result of checkings, the structure of the plate in the fatigue hot spot of the longitudinal incision corner was optimized to make the stress transition smoothly and the fatigue life meet the design requirements. |
