面向可适应性的产品平台功能需求建模与分析

The modeling and analysis of functional requirements for adaptability-oriented product platform

为增强大规模定制下产品族设计的适应性能力,基于客户需求分析,对产品的功能要求进行分析并将其分成三类,结合公理设计和通用设计理论,以元模型描述产品的功能结构概念,提出了一种面向可适应性的产品平台功能需求建模与分析方法。将客户对产品的需求转化为产品功能要求,形成功能概念空间,选择相应的结构概念,并将其组合成结构概念空间。然后根据功能-结构映射,建立并重排设计矩阵,通过对功能要求与设计参数对应关系及敏感性分析,确定产品平台各类型设计参数。最后以电力液压盘式制动器实例来阐述产品平台功能需求建模与分析过程。

To enhance the adaptability of product family design under mass customization,based on the analysis of customer needs,this paper analyzes the functional requirements of the products and divides them into three categories. Based on the axiom design and general design theory,it also describes the functional structure concept with the meta-model,and proposes the functional requirements modeling and analysis method for adaptability oriented product platform,which transforms customer demand for products into functional requirements of the product,forms functional concept space,select the appropriate structural concepts and combines them into a structural concept space. Then,according to the function-structure mapping,it establishes and rearranges the design matrix,which determines the design parameters of various types of product platform by analyzing the correspondence between functional requirements and design parameters and their sensitivity. Finally,by taking the power-driven hydraulic disc brake as an example,this paper illustrates the functional requirements modeling and analysis process of the product platform.
