摘要:

通過綜合使用性能、環(huán)境負荷和經(jīng)濟成本三個因素，本文建立了基于模糊矩陣理論的金屬材料生態(tài)設(shè)計多指標評價模型，并應(yīng)用于鋼鐵、鋁合金、鎂合金三種典型車用金屬材料的生態(tài)設(shè)計。研究結(jié)果顯示，就性能而言，鋼鐵材料的綜合性能優(yōu)于鋁合金材料和鎂合金材料，其性能單一化指標分別比二者高8.25%和3.89%；就環(huán)境負荷而言，鋁合金材料的生命周期環(huán)境負荷低于鎂合金材料和鋼鐵材料，其環(huán)境負荷單一化指標分別比二者低10.68%和22.59%；綜合考慮不同設(shè)計因素，針對汽車前端部件制造，鋁合金材料的生態(tài)設(shè)計實施效果優(yōu)于鋼鐵材料和鎂合金材料。

Abstract:

Through integrating three designing factors, i.e., physical performance, environmental load, and economic cost, this study tentatively established a fuzzy-matrix theory based eco-design model for metal materials, and applied this model to the eco-design of three typical metal materials for automobile, i.e., steel, aluminum, and magnesium. The results show that, regarding the physical properties, steel is more advantageous than aluminum and magnesium towards the demand of automobile industry, and steel’s integrated indictor of physical-performance is 8.25% and 3.89% higher than those of aluminum and magnesium, respectively; with respect to the environmental load, aluminum is more advantageous than steel and magnesium, and the single score of life cycle assessment of aluminum is 10.68% and 22.59% lower than those of magnesium and steel, respectively; in general, integrating various designing factors, the eco-design implementation effect of aluminum is more conspicuous than those of steel and magnesium towards the application in automobile industry.
