【摘要】：機電產(chǎn)品生命周期評價技術(shù)(Life Cycle Assessment,LCA)是綠色制造前沿技術(shù)之一,同時也是實施綠色設(shè)計和制造的關(guān)鍵和共性基礎(chǔ)技術(shù)。目前,國內(nèi)對LCA技術(shù)的需求日益強烈,但與歐美日發(fā)達國家相比,LCA技術(shù)和軟件工具還相當落后,而國外LCA軟件工具尚無法適應(yīng)我國國情和制造業(yè)水平,尤其缺乏反映我國國情和制造業(yè)現(xiàn)狀、系統(tǒng)、準確的LCA底層數(shù)據(jù)庫、知識庫和方法庫支持,嚴重影響了我國LCA研究和企業(yè)應(yīng)用的開展。在此背景下,本文對機電產(chǎn)品LCA方法及其支持工具進行了重點研究,可以為中國LCA發(fā)展提供必要的方法和數(shù)據(jù)支持,為企業(yè)LCA的應(yīng)用提供數(shù)據(jù)積累和案例參考。 本文在分析國內(nèi)外綠色設(shè)計、LCA技術(shù)及軟件工具研究現(xiàn)狀的基礎(chǔ)上,重點對以下幾個方面進行了研究。 (1)在有關(guān)LCA定義及技術(shù)框架研究的基礎(chǔ)上,針對當前LCA研究的局限性,結(jié)合機電產(chǎn)品的特點,建立了LCA中機電產(chǎn)品系統(tǒng)模型,詳細分析了機電產(chǎn)品系統(tǒng)的信息組成。然后基于此系統(tǒng)模型,在整個產(chǎn)品生命周期內(nèi)定義了產(chǎn)品的環(huán)境屬性。按照環(huán)境影響因素,對其生命周期的不同階段進行了研究,建立了環(huán)境因素識別表,按照此識別表從低污染、低毒等方面研究識別環(huán)境因素和顯著環(huán)境因素。最后基于生命周期評價方法學框架的研究,針對機電產(chǎn)品提出了具體的生命周期評價過程和方法。 (2)在當前國內(nèi)外LCA數(shù)據(jù)庫現(xiàn)狀研究的基礎(chǔ)上,研究了面向機電產(chǎn)品的符合中國國情的生命周期評價數(shù)據(jù)庫,提出了基于過程的清單分析方法,建立了基于過程的LCA數(shù)據(jù)庫三層結(jié)構(gòu)模型,并根據(jù)LCA數(shù)據(jù)庫三層結(jié)構(gòu)模型對LCA數(shù)據(jù)庫進行了概念結(jié)構(gòu)設(shè)計、對象屬性分析和邏輯結(jié)構(gòu)設(shè)計。 (3)結(jié)合上述基于機電產(chǎn)品的LCA方法和LCA數(shù)據(jù)庫三層結(jié)構(gòu)模型,研究了MLCA系統(tǒng)的目的和功能,選取Visual Studio.NET集成開發(fā)環(huán)境為開發(fā)平臺,B/S模式為系統(tǒng)開發(fā)模式,設(shè)計了系統(tǒng)的總體框架。針對此框架,利用C#及SQL Server技術(shù),對系統(tǒng)進行了接口定義、數(shù)據(jù)庫關(guān)聯(lián)、接口實現(xiàn)等詳細設(shè)計。最后實現(xiàn)了系統(tǒng)的直觀顯示,即對系統(tǒng)操作界面的設(shè)計。 (4)基于機電產(chǎn)品系統(tǒng)模型及相關(guān)環(huán)境因素的識別,利用所開發(fā)的MLCA系統(tǒng),對Y80M1-4-0.55型電機進行了生命周期評價。
[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.
