【摘要】：日益严峻的资源和环境问题已经成为制约我国经济发展的瓶颈,同时欧美等发达国家针对我国机电产品的出口形成了绿色贸易壁垒。绿色设计制造已经成为一种趋势,是改善我国机电产品环境属性、提高产品国际竞争力的重要举措。生命周期评价技术(Life Cycle Assessment, LCA)是绿色设计绿色制造的关键支撑技术。现有的LCA方法大都是针对已有的产品进行数据收集,建立评价模型进行环境影响评价；缺少对一般设计信息的利用和对潜在设计信息的挖掘,无法适用于方案设计阶段。方案设计作为产品设计的重要阶段,是产品设计能否成功的关键,决定了产品性能的70%-80%。如何在方案设计阶段对产品全生命周期环境和资源属性做出正确评价,是绿色设计能否成功的关键。在此背景下,本文对机电产品方案设计阶段的绿色设计方法进行重点研究,建立针对方案设计阶段的产品环境属性快速评价及决策模型,支持我国机电产品的绿色设计。 (1)在分析绿色设计内涵的基础上建立了针对机电产品方案设计阶段的绿色设计模型。针对模型的需要提出了绿色特征的概念,分析了绿色设计过程的设计信息,并探讨了绿色特征的内涵,对产品方案设计阶段的设计信息和潜在设计信息进行挖掘,以绿色特征化建模的方式将产品设计信息转化为绿色特征值；并以模糊层次分析法分析了应用绿色特征进行设计方案决策的方法。 (2)建立了面向机电产品方案设计的绿色特征创建模型。首先研究产品方案设计信息的表达方法,以零件层-部件层-装置层-功能层-方案层的由叶到根的树形结构表达设计信息,并建立了便于绿色特征提取的设计信息表达矩阵；再根据生命周期环境影响评价的思想分析了绿色特征的类型及分类特征化处理方法,建立了绿色特征的筛选矩阵。最后阐述了绿色特征筛选聚合的具体方法,建立了以绿色特征为基础的产品方案设计信息表达模型。 (3)在本文阐述的理论、方法的基础上应用C#编程语言及SQL Sever数据库技术进行了绿色设计软件系统的开发。分为操作层、算法层、数据库层对设计工具进行总体设计；建立了基础数据库、用户数据库及过程数据库；分四个模块对操作界面进行设计。 (4)以Y80小型通用电机为例研究了绿色特征的建模过程,获得该电机的绿色特征。
[Abstract]:The increasingly severe problems of resources and environment have become the bottleneck restricting the economic development of our country. At the same time, developed countries such as Europe and America have formed green trade barriers against the export of China's mechanical and electrical products. Green design and manufacturing has become a trend, which is an important measure to improve the environmental properties of mechanical and electrical products and enhance the international competitiveness of products. Life Cycle Assessment, LCA) is the key supporting technology of green design and green manufacturing. Most of the existing LCA methods are used to collect data for existing products and establish evaluation models for environmental impact assessment, and lack of general design information and mining of potential design information, which can not be used in the stage of project design. As an important stage of product design, scheme design is the key to the success of product design. It is the key to the success of green design that how to evaluate the environment and resource attributes of the whole product life cycle in the project design stage. Under this background, this paper focuses on the green design method in the design phase of electromechanical products, and establishes a rapid evaluation and decision model for the environmental properties of the products in the phase of the scheme design to support the green design of mechanical and electrical products in China. 1) based on the analysis of the connotation of green design, a green design model for the design stage of mechanical and electrical products is established. According to the needs of the model, the concept of green feature is put forward, the design information of green design process is analyzed, the connotation of green feature is discussed, and the design information and potential design information of product scheme design stage are excavated. The product design information is transformed into green feature value by green feature modeling, and the method of applying green feature to design scheme decision is analyzed by fuzzy analytic hierarchy process (FAHP). The green feature creation model for electromechanical product scheme design is established. Firstly, the representation method of product scheme design information is studied, and the design information is expressed by the tree structure from leaf to root of part layer, component layer, device layer, function layer and scheme layer, and the expression matrix of design information is established which is convenient to extract green features. Then, according to the idea of life cycle environmental impact assessment, the types of green features and the treatment methods of classification characteristics are analyzed, and the screening matrix of green features is established. Finally, the concrete method of green feature screening and aggregation is introduced, and the information expression model of product scheme design based on green feature is established. 3) based on the theory and method described in this paper, the green design software system is developed by using C # programming language and SQL Sever database technology. It is divided into operation layer, algorithm layer and database layer. The basic database, user database and process database are established. The operation interface is designed in four modules. The modeling process of green feature of Y80 general purpose motor is studied, and the green feature of the motor is obtained.
