Textile Machinery Modeling Design Based on Analytic Hierarchy Process

目的为了提升纺织机械造型设计的理性化和客观性,量化设计纺织机械的造型问题,提出一种基于层次分析法的纺织机械造型设计方法,并以针织横机的造型设计为例进行分析和验证。方法运用焦点小组法确定针织横机的造型意象,结合形态分析法构建针织横机形态部件的判断矩阵,运用层次分析法获得各主要部件对整体形态的造型贡献值,并通过对代表性样本的形态特点分析,获取各意象维度的造型设计建议并指导设计实践;用层次分析法建立评价模型和判断矩阵,经过评估得到3个设计方案,优选出最佳方案。结论结果表明,运用层次分析法,可以帮助设计师有效地量化分析出设计对象主要部件的造型贡献值,为纺织机械造型设计提供方向和建议,并同时为评估和优选设计方案提供有效的方法,使设计过程更加理性和系统化。

In order to improve the rationality and objectivity of textile machinery modeling design and quantify the problem of textile machinery modeling design,this paper presents a modeling design method of textile machinery based on analytic hierarchy process(AHP).And take the flat knitting machine shape design as a case study to demonstrate the analysis and the verification.Firstly,focus group method is used to determine the shape image of flat knitting machine,combined with shape analysis method,the judgment matrix of the flat knitting machine shape components is constructed,and the modeling contribution value of the main components to the whole shape is obtained by using the analytic hierarchy process.Through the analysis of the morphological characteristics of the representative samples,we can get the design advice of each image dimension and guide the design practice.The evaluation model and judgment matrix were established by analytic hierarchy process,and the three design schemes were evaluated,and the best scheme was selected.The results show that the analytic hierarchy process can help designers quantitatively analyze the modeling contribution values of the main components of the design object,provide direction and suggestions for textile machinery modeling design,and at the same time provide an effective method for evaluating and optimizing the design scheme.Make the design process more rational and systematic.
