摘要
为了得到汽车车身材料CO_2排放和车身轻量化的关系,并对车身材料轻量化发展作出合理预测,该文基于生命周期评价方法,利用生命周期评价专用GaBi建模软件,分析了普通低碳钢、镁合金、铝合金、碳纤维4种车身材料的原材料获取阶段的CO_2排放,得出普通低碳钢CO_2排放最小、铝镁是车身轻量化发展的理想材料,对节能减排具有一定的指导意义。
In order to obtain the relationship between CO2 emission and lightweight of automobile body m aterials,and to make a reasonable prediction of the developm ent of body m aterial lightweight,based on the life cycle assessm ent method,a special modeling software GaBi for life cycle assessm ent is used.The CO2 emissions of raw m aterials of four kinds of body m aterials,such as ordinary low carbon steel,magnesium alloy,aluminum alloy and carbon fiber,are analyzed.It obtains that the ordinary low carbon steel has the lowest CO2 emission and aluminum magnesium is the ideal m aterial for the developm ent of body weight reduction,which has certain guiding significance for energy saving and emission reduction.
