[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.
