摘要:

以52 m散装水泥船为研究对象, 利用有限元分析软件, 分析该船罐体支撑结构局部强度, 在局部强度不满

足规范要求的情况下, 对局部结构提出三种改进方案:改变支撑结构横向板的厚度、增加支撑板结构的垂直

扶强材和改变支撑结构板材属性。在通过计算验证应力计算值均满足规范要求的基础上, 借助模糊综合评

判理论对改进后三种方案进行比较分析, 通过确定评价对象的因素集、确定评价因素的权重向量、确定评

价对象的评语集、指标量化处理、二级模糊评判和一级模糊评判等流程, 确立方案Ⅲ为最优加强方案。

Abstract:

Taking the 52 m bulk cement ship as a research focus, the finite element analysis software is

used to analyze the local strength of a ship’s tank supporting structure. Under the condition

that the local strength does not meet the specification requirements, three improvement

schemes are proposed: changing the thickness of supporting structural transvers plate,

increasing vertical stiffeners for supporting structure and changing the properties of the

structure plate. On the basis of calculating and verifying that the calculated values of the

stresses all meet the requirements of the specification, the fuzzy comprehensive evaluation

theory is used for comparing and analyzing the three improved schemes. By determining the

factor set of the evaluation objects, the weight vector of the evaluation factors, and the

evaluation objects’ comment set as well as quantitative indicator processing, secondary fuzzy

evaluation and first-level fuzzy evaluation etc., the scheme Ⅲ is determined to be the

optimal reinforcement one.
