【摘要】:机电产品生命周期评价技术(Life Cycle Assessment,LCA)是绿色制造前沿技术之一,同时也是实施绿色设计和制造的关键和共性基础技术。目前,国内对LCA技术的需求日益强烈,但与欧美日发达国家相比,LCA技术和软件工具还相当落后,而国外LCA软件工具尚无法适应我国国情和制造业水平,尤其缺乏反映我国国情和制造业现状、系统、准确的LCA底层数据库、知识库和方法库支持,严重影响了我国LCA研究和企业应用的开展。在此背景下,本文对机电产品LCA方法及其支持工具进行了重点研究,可以为中国LCA发展提供必要的方法和数据支持,为企业LCA的应用提供数据积累和案例参考。 本文在分析国内外绿色设计、LCA技术及软件工具研究现状的基础上,重点对以下几个方面进行了研究。 (1)在有关LCA定义及技术框架研究的基础上,针对当前LCA研究的局限性,结合机电产品的特点,建立了LCA中机电产品系统模型,详细分析了机电产品系统的信息组成。然后基于此系统模型,在整个产品生命周期内定义了产品的环境属性。按照环境影响因素,对其生命周期的不同阶段进行了研究,建立了环境因素识别表,按照此识别表从低污染、低毒等方面研究识别环境因素和显著环境因素。最后基于生命周期评价方法学框架的研究,针对机电产品提出了具体的生命周期评价过程和方法。 (2)在当前国内外LCA数据库现状研究的基础上,研究了面向机电产品的符合中国国情的生命周期评价数据库,提出了基于过程的清单分析方法,建立了基于过程的LCA数据库三层结构模型,并根据LCA数据库三层结构模型对LCA数据库进行了概念结构设计、对象属性分析和逻辑结构设计。 (3)结合上述基于机电产品的LCA方法和LCA数据库三层结构模型,研究了MLCA系统的目的和功能,选取Visual Studio.NET集成开发环境为开发平台,B/S模式为系统开发模式,设计了系统的总体框架。针对此框架,利用C#及SQL Server技术,对系统进行了接口定义、数据库关联、接口实现等详细设计。最后实现了系统的直观显示,即对系统操作界面的设计。 (4)基于机电产品系统模型及相关环境因素的识别,利用所开发的MLCA系统,对Y80M1-4-0.55型电机进行了生命周期评价。
[Abstract]:Mechanical and electrical product life cycle assessment (Life Cycle Assessment,LCA) is one of the leading technologies of green manufacturing, and it is also the key and common basic technology of green design and manufacturing. At present, the domestic demand for LCA technology is increasingly strong, but compared with the developed countries in Europe, the United States and Japan, LCA technology and software tools are still quite backward, while foreign LCA software tools are still unable to adapt to China's national conditions and manufacturing level. In particular, the lack of support to reflect the situation of our country and manufacturing industry, system, accurate LCA database, knowledge base and method base has seriously affected the development of LCA research and enterprise application in our country. Under this background, this paper focuses on the LCA method and its supporting tools for mechanical and electrical products, which can provide necessary methods and data support for the development of LCA in China, and provide data accumulation and case reference for the application of LCA in enterprises. Based on the analysis of the research status of green design, LCA technology and software tools at home and abroad, this paper focuses on the following aspects. The main contents are as follows: (1) on the basis of the research on the definition and technical framework of LCA, aiming at the limitation of current LCA research and combining with the characteristics of mechanical and electrical products, the mechanical and electrical product system model in LCA is established, and the information composition of the electromechanical product system is analyzed in detail. Then, based on this system model, the environmental properties of the product are defined throughout the product life cycle. According to the environmental influence factors, the different stages of their life cycle were studied, and the identification table of environmental factors was established. According to the identification table, the environmental factors and significant environmental factors were identified from the aspects of low pollution, low toxicity and so on. Finally, based on the research of life cycle assessment methodology framework, specific life cycle assessment processes and methods for electromechanical products are proposed. (2) on the basis of the current research of LCA database at home and abroad, the life cycle assessment database for mechanical and electrical products is studied, and the process-based inventory analysis method is put forward. The three-tier structure model of LCA database based on process is established. According to the three-tier structure model of LCA database, the conceptual structure, object attribute analysis and logical structure design of LCA database are carried out. (3) combining the above-mentioned LCA method based on electromechanical products and the three-tier structure model of LCA database, the purpose and function of MLCA system are studied. The integrated development environment of Visual Studio.NET is chosen as the development platform, and the mode of BES is used as the development mode of the system. The overall framework of the system is designed. According to this framework, using C # and SQL Server technology, the system interface definition, database association, interface implementation and so on are designed in detail. Finally, the visual display of the system is realized, that is, the design of the operating interface of the system. (4) based on the model of mechatronics system and the identification of related environmental factors, the life cycle of Y80M1-0.55 motor is evaluated by using the developed MLCA system.
