汽车车架的成形工艺创新

Innovative Forming Technologies for Space Frames

成形工艺尤其是传统方式的板材拉深，是汽车工业的核心技术。但是，与新的材料和半成品材料一样，新的成形工艺也变得越来越重要，因此，对将来的铝制汽车生产而言，必须对这些技术进行全面的分析方可做出最为有效的选择。文章以 Audi车为例，重点讨论铝质材料及工艺技术的发展状况。

Forming technologies especially deep drawing of sheets in conventional way,are certainly the core businesses of the car industry.But,with new materials and new semi materials,new forming technologies are becoming more important.For future aluminium cars therefore,a thorough examination of these technologies is necessary for the purposeful selection of the most efficient ones.Take AUDI for example,developmental state of aluminium materials and forming technologies are discussed in the article.
