随着人口的增加,汽车保有量飞速增长,汽车消耗的能源也越来越多。人们的购车观念从开始的追求大排量、强动力向小排量、经济性转变。如何在汽车行业内实现节能减排,轻量化是一条关键的途径。文章通过市场调查和构建数据库,同时利用先进汽车模拟软件CRUISE,以某典型乘用车车型为基础,在典型工况下分析轻量化与节油之间的关系,通过逐级的质量变化,得出了明确的轻量化与节油关系的评价区间。
As the population increases, car ownership grows rapidly, and cars consume more and more energy. People’s car concept from the beginning of the pursuit of large displacement, strong momentum to small displacement, economic change. How to achieve energy-saving emission reduction in the automotive industry, lightweight is a key way. Based on the market research and database construction, CRUISE, an advanced automotive simulation software, is based on a typical passenger car model. Under typical conditions, the paper analyzes the relationship between light weight and fuel efficiency. Through the gradual change of quality, Out of a clear light of the relationship between fuel economy evaluation interval.
