| 摘 要： | 以3型目标船为样本,通过理论推导和实船计算,对散货船油船协调共同规范(HCSR规范)疲劳简化算法评估中舱壁位移引起纵骨端部附加应力(公式法和系数法)进行分析,结果表明:理论公式法适用于散货船,不适用于油船;油船应采用系数法。

| Abstract: | Taking 3 target ships as examples , the method to calculate the additional stress （ formula method and coefficient method） of longitudinal end connection introduced by bulkhead displacement was researched for the fatigue assessment in Com -mon Structural Rules for Bulk Carriers and Oil Tankers （ HCSR） through theoretical derivation and full scale calculation .The nu-merical results showed that the formula method is suitable for bulk carriers while the coefficient method is suitable for oil tankers . |
