基于公理设计和模块关联矩阵的产品族设计耦合分析

摘要/Abstract

摘要： 针对产品族设计耦合问题，分析比较了其与单一产品设计耦合的异同之处，提出了一种基于公理设计和模块关联矩阵的耦合分析方法。以公理设计为指导，进行功能需求分析及类型划分；分析了产品族客户需求、功能要求、设计参数和模块之间的对应关联关系，考虑适应性设计参数的影响度并将其分为两类以确定产品族的共性和差异性；从策略层面减弱产品族设计的耦合性。从操作层面的角度，根据设计参数零部件间的综合关联关系，通过聚类重构生成几个相互之间具有较小依赖度的模块，分析设计参数间的变更传播关系，建立产品族模块关联矩阵；从模块内部的耦合和模块之间的耦合两方面探讨了关联特性。最后通过电力液压盘式制动器实例阐述了产品族设计耦合分析过程。

Abstract: For the coupling problems of product family design, the similarities and differences of design coupling between product family and single product were analyzed and compared, and a method of analyzing and disposing coupling design for product family was presented based on axiomatic design and modular incidence matrix. The axiomatic design theory was utilized as framework to analyze and classify functional requirements. The corresponding relationships among customer's demands, functions, components and design parameters of product platform were analyzed, and the influences of adaptive design parameters were considered to be divided into two categories to identify commonality and differences of product family. This may weaken design coupling from strategic level of platform plan. In the view of platform operation level, according to comprehensive correlation degree among design parameters, any modules were generated by clustering reconstruction with less dependent degree in design structure matrix. The change propagation of design parameters were analyzed, and modular incidence matrix was established. Then from the coupling inside modules, and among design parameters with different modules, the detailed analyzing and disposing method was given. Finally, an example of electro-hydraulic disc brake was provided to illustrate the analysis and disposal processes on the proposed method.

Key words: product family design, coupling analysis, axiomatic design, modular incidence matrix, disc brake
