为了对比新的散货船、油船协调共同规范和旧的双壳油船结构共同规范,选取两艘具有水平桁结构和两艘具有槽型舱壁油船作为研究对象,对这两种不同结构形式的油船,分别按HCSR和CSR规范的要求,进行加载分析计算疲劳寿命,并基于CSR规定,比较底边舱下折角位置处的疲劳寿命。认为HCSR疲劳载荷选取更加合理,评估体系更加严格。
為瞭對比新的散貨船、油船協調共同規範和舊的雙殼油船結構共同規範,選取兩艘具有水平桁結構和兩艘具有槽型艙壁油船作為研究對象,對這兩種不同結構形式的油船,分彆按HCSR和CSR規範的要求,進行加載分析計算疲勞壽命,併基于CSR規定,比較底邊艙下摺角位置處的疲勞壽命。認為HCSR疲勞載荷選取更加閤理,評估體繫更加嚴格。

For comparing the two fatigue assessment system of oil tanks given by HCSR and CSR -OT, two oil tanks with hor-izontal stringer and corrugated bulkhead were selected as research objects .The hot spot stress FEA was carried out with two kind of different applied loads according to HCSR and CSR-OT respectively so as to calculate the fatigue life .The results of fatigue life of the hopper knuckle were compared , showing that HCSR has more reasonable loads and more strict assessment system .
