清华大学汽车工程研究院常务副院长宋健表示,实现轻量化有两种途径,一是,优化结构,就是把现在不需要的重量减下去。“我们的一项研究显示,在满足相关要求的情况下,通过优化结构,车重可以减少30%左右。”另外一种就是,找比较轻的、单位强度大的材料来替代原来使用的材料。 Song Jian, executive vice president of Automotive Engineering Institute of Tsinghua University, said there are two ways to achieve weight reduction: First, optimize the structure, that is, the weights do not need to go down now. “One of our studies shows that by optimizing the structure, the weight can be reduced by about 30% if the relevant requirements are met.” Alternatively, look for lighter, bulky materials to replace the original ones s material.
