摘要
根据IACS2014年1月推出的CSR-H，对目前CSDC设计的18万吨散货船进行符合CSR-H设计。分别运用美国船级社的CA Stage 1程序和CSR-H Bulk Check Stage 2程序进行规范计算和有限元计算，给出满足CSR-H要求的货舱区结构重量对于CSR规范的增加量。主要内容如下：一、比较CSR-H与CSR对散货船要求的差异，分析CSR-H对散货船设计的影响。二、对货舱区各个横剖面进行规范计算，研究CSR-H对板材和型材尺寸的新要求，分析各结构部位与满足CSR船型结构存在差异的原因。三、应用直接计算法对全船货舱区进行屈服和屈曲强度评估，比较基于CSR-H要求的计算结果与CSR要求结构尺寸存在的差异。
The current 180 000 t bulk carrier designed by CSDC is redesigned according to the harmonised common structural rules （CSR-H）, which has been proposed by IACS in January, 2014. The increment of structural weight in cargo hold region that meets the requirements of CSR-H is calculated by CA stage 1 and CSR-H Bulk Check stage 2 programs of American Bureau of Shipping （ABS）, as well as the ifnite element analysis. Firstly, it compares the requirements of bulk carriers in CSR-H with those in common structural rules （CSR）, and analyzes the impact effect of the new requirements in CSR-H on the design of bulk carriers. Secondly, it studies the new requirements of the grillage and scantlings in CSR-H from the rule calculations of each transverse section in the cargo hold region, and analyzes the reason that each structure differs from the structure following with CSR. Lastly, it evaluates the yielding strength and the buckling strength of all cargo hold region by the direct calculation, and compares the scantlings calculated by the requirements of CSR-H with those calculated by the requirements of CSR.
