【摘要】：随着我国经济的飞速发展,汽车制造业迎来了高速发展的机遇。然而目前我国汽车制造业的发展主要依靠能源、资源的高投入,这种发展模式在一定程度上导致了我国资源的短缺与环境的污染。因此,为了应对市场竞争,促进汽车产业的绿色、健康发展,必须在汽车产品的设计过程中综合考虑汽车产品的设计效率与环境属性。将产品生命周期评价与CAD设计软件集成,实现在汽车产品设计过程中对其环境性能的实时评估,这对提高汽车产品的设计效率与环境性能具有一定的意义,是汽车产品设计的重要研究方向。本文在对汽车产品结构与制造工艺分析的基础上进行了其生命周期碳排放分析,确定了汽车产品生命周期碳排放主要影响因素,并提出了汽车产品进行低碳设计与制造的实施策略;基于汽车产品生命周期碳排放特性,提出了产品生命周期碳排放量化方法,运用该方法对汽车产品生命周期碳排放进行了量化研究,构建了其生命周期碳排放量化模型,并从汽车产品的结构、材料、工艺、拆卸回收的角度,构造了汽车产品低碳评价指标,提出了识别汽车零部件低碳优化设计潜能的方法,建立了评价结果与设计建议的反馈机制;对Creo二次开发技术、数据库技术及特征识别与匹配技术进行了分析、研究,提出了汽车典型零部件低碳设计集成系统的理论实现方案;开发了汽车典型零部件低碳设计集成系统,实现了在零件设计过程中实时评价零件的碳排放特性并反馈低碳改进建议;最后,以汽车发动机的设计过程为例,阐述了集成系统的运行流程与操作方法,验证了该集成系统的有效性。
[Abstract]:With the rapid development of our country's economy, the automobile manufacturing industry has ushered in the opportunity of rapid development. However, the development of our country's automobile manufacturing industry mainly depends on the high investment of energy and resources. To a certain extent, this mode of development has led to the shortage of resources and environmental pollution in China. Therefore, in order to cope with the market competition, promote the green and healthy development of the automobile industry. The design efficiency and environment attribute of automobile product must be considered comprehensively in the process of automobile product design. Product life cycle evaluation and CAD design software should be integrated. To realize the real-time evaluation of its environmental performance in the process of automotive product design, which has certain significance to improve the design efficiency and environmental performance of automotive products. It is an important research direction of automobile product design. Based on the analysis of automobile product structure and manufacturing process, this paper analyzes the carbon emission of its life cycle. The main influencing factors of carbon emission in automobile product life cycle are determined, and the implementation strategy of low carbon design and manufacture for automobile product is put forward. Based on the carbon emission characteristics of automobile product life cycle, the method of product life cycle carbon emission is put forward, and the quantitative study of automobile product life cycle carbon emission is carried out by using this method. The life-cycle carbon emission model is constructed, and the low carbon evaluation index of automobile products is constructed from the perspective of structure, material, process, disassembly and recovery of automobile products. The method of identifying the potential of low carbon optimal design of automobile parts is put forward, and the feedback mechanism of evaluation results and design suggestions is established. The second development technology of Creo, database technology and feature recognition and matching technology are analyzed, and the theory realization scheme of low carbon design integration system for typical automobile parts is put forward. A low carbon design integrated system for typical parts of automobile is developed, which can evaluate the carbon emission characteristics of parts in real time and give feedback to the suggestions for low carbon improvement in the process of part design. Finally, taking the design process of automobile engine as an example, the operation flow and operation method of the integrated system are expounded, and the validity of the integrated system is verified.
