- 摘要：基于生命周期评价(LCA)理论,运用GaBi软件建模,采用EDIP 2003评价体系,对某款商用车铝合金轮辋和钢制轮辋的生命周期环境影响进行了评价和对比分析.结果表明:在原材料获取阶段铝合金轮辋对环境的影响要远远大于钢制轮辋;制造阶段两种轮辋对环境的影响相差不大;使用阶段钢制轮辋对环境的影响大于铝合金轮辋;综合所有阶段来看,当车辆总行驶里程低于11.6万km时,铝合金轮辋对环境的影响更大,超过11.6万km后,钢制轮辋对环境的影响更大.
- Abstract：Based on the theory of life cycle assessment (LCA), a new model is built by the GaBi software to assess and analyze the life cycle environmental impacts of a certain commercial vehicle rim made of aluminum alloy and steel by means of the EDIP 2003 assessment system. The result shows that the environmental impact of the aluminum alloy rim is far greater than steel rim during the stage of raw material acquirement, while there is little difference during the manufacturing stage. The environmental impact of the steel rim is greater than that of the aluminum alloy rim in the employment stage. In view of all stages, the life cycle environmental impact of steel rim is less than that of aluminum rim when the accumulative distance of the vehicle is less than 116000 km.
