基于装配关系的船舶分段组立划分方法
|
摘要
为提升船舶分段装配的工艺设计效率与智能化水平,提出了一种基于装配关系的组立结构划分方法.通过分析船舶分段的焊接形式与装配工艺特点,考虑零部件间接关联关系对装配紧密度的影响,建立了分段装配强度关系矩阵.在此基础上,利用模糊聚类分析理论构建分段组立结构划分的数学模型,并针对聚类结果与划分粒度不唯一的问题,提出了以装配单元内部聚合度为评价指标的方案优选方法.最后,以两个具有代表性分段为例进行验证,结果表明该方法可以实现分段组立结构的自动合理划分,并且能够自主决策方案划分的粒度.
In order to improve the intelligent level and efficiency of ship block assembly process design, an assembly unit partitioning method was studied based on assembly relationship.First,by analyzing welding forms and assembly process characteristics,the strength matrix of block assembly relationship was established considering indirect correlation between parts.Then,based on fuzzy clustering theory,a mathematical model for block assembly unit partition was constructed.Aiming at the problem of granularity diversification in fuzzy cluster analysis,a clustering scheme evaluation function was designed based on the degree of polymerization within assembly unit.Finally, the method was applied to two representative blocks,and results show that the method can partition assembly unit and determine partition granularity automatically.
