Abstract

Abstract:

This paper analyzed the GREET model of USA Argonne national laboratories, which made energy consumption evaluation with the whole life cycle assessment theory for automotive lightweight. First the boundaries of energy evaluation system was confirmed, and the calculation model for the energy consumption of the main material for car model was established, and the method for the energy consumption calculation in the phase of use, assembly and scrap recovery was suggested. This paper selected Prius as the example, with the calculation model, using the GREET software, a comparative analysis of energy consumption and a sensitivity analysis for the whole life cycle of the lightweight Prius and a normal Prius were made, the results show that the automotive lightweight can effectively reduce energy consumption throughout the life cycle. 

Key words: automotive lightweight, life-cycle assessment, energy consumption calculation model, GREET software, Toyota Prius

摘要：

针对美国Argonne国家实验室开发的GREET模型，运用全生命周期评价理论对汽车轻量化进行能耗评价。首先确立了能耗评价系统的边界，然后建立了适用于汽车主要材料的能耗计算模型，并提出了汽车使用、组装以及报废回收阶段的能耗计算方法。选取丰田Prius车型作为实例，结合计算模型和GREET软件，对轻量化Prius及普通的Prius汽车车身进行全生命周期的能耗比较计算及敏感性分析。结果表明，汽车轻量化可有效降低汽车的整个生命周期能耗。
