基于瞬-稳态能量联动分析的机床节能方法及人机协同碳排放优化研究

CNC machine tools are widely used in discrete manufacturing, which consume a large amount of energy and result in significant carbon emissions. Energy-saving and emission reduction potential for CNC machine tools is great. It is of great theoretical and practical value to study energy and carbon emissions modeling and energy-saving and emission-reduction methods of CNC machine tools. The energy consumptions and carbon emissions of transient states of machine tool and operator are often overlooked. In fact, carbon emissions of transient states and operator are an important part of carbon emissions of machine-operator system and cannot be ignored. The energy consumptions/carbon emissions of transient states and operator will be considered in this project. Typical machine-operator system in discrete manufacturing is taken as the research object. Linear/nonlinear fitting, transient-steady energy linkage analysis and multi-objective optimization methods will be used to achieve project objectives. The project focuses on the research of energy characteristics and energy modeling method of transient states of CNC machine tools, transient-steady energy linkage analysis method, comprehensive energy optimization method of machine tools considering transient-steady energy interaction, carbon emission rate modeling for activities of operator, and carbon emissions co-optimization method of machine-operator system during non-cutting process. This project aims to guide the best coordination of CNC machine tools and operators, to provide effective theoretical guidance and method support for energy-saving, low-carbon and high efficiency operating of machine-operator system. The outcome of this project has a very important guiding significance for the energy-saving and emission reduction of manufacturing industry.
