铝在汽车材料中的运用及展望

近年来国内外学者在汽车轻量化研究方面取得了诸多成果，但仍然存在较多问题，研究方法仍然集中在对汽车车身的一些零部件用低密度材料进行替换，这些方法大多数仍是凭经验设计，文章在前人的研究基础上，对汽车轻量化设计进行了较为系统和深入地研究，在确保汽车综合性能指标的前提下，尽可能地降低汽车产品自质量，达到减轻质量、降耗及安全的综合指标，并且介绍了铝的性质及铝合金的特点，同时列举了铝在汽车上应用的一些实例，同时也提出了发展趋势。

The Application of Aluminum in Automotive Materials and its Prospect

In recent years,domestic and foreign scholars have made achievements in lightweight research,but there are still many problems,research method is still concentrated on some parts of car body replaced with low-density material,most of these methods are still rule of thumb design.Based on the basis of previous studies,a more systematic and in-depth research of automotive lightweight design is conducted.Under the premise of ensuring comprehensive performance of car,reduce weight of product itself as much as po...
