大型油船槽形舱壁结构形式设计及模糊综合评判

文章从规范设计角度入手,设计采用单面斜壁顶凳、双面直壁顶凳、双面直壁较矮顶凳和横舱壁无顶凳四种顶凳结构形式的槽形舱壁,并进行强度评估.在满足规范要求的前提下,考虑到最大货舱舱容、最轻空船重量、最小应力、最佳工艺性等主要技术指标进行模糊综合评判,优选出综合经济性最好的结构形式.

Structural Design and Fuzzy Comprehensive Evaluation for Corrugated Bulkheads of Large Oil Tanker

Based on the specification of design,the article developed four designs of corrugated bulkheads with different types of upper stool such as single gradient-wall upper stool,double straight-wall upper stool,double lower straight-wall upper stool and the transverse bulkheads with non-upper stool,and evaluate the stress.Under the premise of meeting the regulatory requirements,fuzzy comprehensive evaluation was done to the major design criteria of largest tank capacity,minimum lightweight,minimum stress and mos...
