汽车密封条可重构生产线全生命周期评估

Life Cycle Assessment of Reconfigurable Manufacturing System for Automobile Weather Strip

概述了LCA(L ife cycle assessm en t,全生命周期评价)基本内容,结合汽车车窗密封条可重构生产线的研究,给出了其系统边界、模型和设定。针对可重构生产线生命周期各个阶段,分析图表显示产生选定环境影响物质的数量,包括CO2、有害物质和能源消耗。LCA分析软件E co-IT计算结果显示,该密封条生产线的环境影响指数有11×103Pt来源于系统的使用阶段。超过5×103Pt的影响指数来源于加工或重建一个新系统,而通过重构系统只产生少于0.30×103Pt影响指数。本文旨在采用一个科学方法来评价可重构制造系统生命周期的能源消耗和环境影响因素,并给出可重构制造系统有益于可持续发展这一结论。

Life cycle assessment （LCA） is presented. System boundaries, the model and assumptions are given by combining the reconfigurable manufactureing system （RMS） study of the automobile weather strip. Result tables present the selected environmental flows, including CO2, particulate matter, and energy consumption, for each of the RMS life cycle stages. Results of the LCA show that the environmental impact factor 11 × 10^3Pt may be attributed to the use phase of RMS. More than 5 × 10^3Pt is attributed to the manufacturing stage or rebuilding a new system, whereas less than 0.3 × 10^3Pt is attributed to reconfigure the system. This paper adopts a scientific approach to assess energy and environmental impacts over the life cycle of RMS, and to give a result.
