摘要
文章选取车身框架作为评价对象,对4种车身材料(普通低碳钢、高强度钢、铝合金和镁合金)的生命周期各主要阶段进行了清单分析,计算得出了各车身材料全生命周期的能耗与CO_2排放结果。结果显示,采用轻质材料能够在全生命周期过程中有效降低能耗与CO_2排放。并运用敏感性分析,分别探讨了汽车使用寿命内的总行驶里程和替代普通低碳钢的轻质材料质量大小对车身材料全生命周期能耗与CO_2排放的影响规律。
Body frame is selected as subject to assessment. The life cycle inventory data of the various major phases of four auto body materials （ low - carbon steel, high - strength steel, aluminum and magnesium alloys） are analyzed, and the life cycle energy consumption and CO2 emissions of vari- ous auto body materials are calculated. The results show that using lightweight materials can effectively reduce life cycle energy consumption and CO2 emissions. Sensitivity analysis is used to discuss respectively how the change of total mileage in vehicle＇s service life and lightweight material mass replacing low - carbon steel would affect the life cycle energy consumption and CO2 emissions of auto body materials
