摘要
围绕汽车生态设计的理念,以生产1件汽车前端模块(零部件)轻量化设计为切入点,使用生命周期评价(LCA)的方法,对比分析传统纯钢制造方案和铝钢、塑料轻量化制造方案在能耗与环境的影响差异,运用Ga Bi Ts软件计算得出,铝钢和塑料方案比纯钢方案在汽车行驶阶段中节油8.43 L和21.53 L。同时,在整个生命周期过程中温室气体排放分别减少70.352 kg CO_2e和184.079 kg CO_2e,以定量化分析明确轻量化设计对环境影响优于传统设计。
Based on the concept of automobile eco - design, this paper started with the light- weight design of 1 piece automotive front module （components） and a comparison analysis among the traditional plan made by pure steel and the lightweight plan made by aluminum steel or plastic is con- ducted. It is calculated by GaBiTs that the aluminum steel plan or plastic plan would save 8.34 L and 21.53 L oil respectively during driving stage and lead to a reduction of greenhouse gases emission about 70. 352 kgCO2e and 184. 079 kgCO2e through the whole life cycle. It is concluded that the environ- mental impact of lightweight design is better than traditional design through quantitative analysis.
