摘　　要：介绍了一种正面碰撞工况中的乘用车前纵梁变形模式,并通过使用截面分析和计算方法,实现了该变形模式的可控设计,很大程度上省略了当前普遍存在耗时较多的试错式设计方法,并提高了结构材料利用率。设计结果同整车有限元碰撞模拟分析结果中纵梁的变形模式实现匹配。This paper introduces a kind of sedan front side rail front impact deformation, which can be sketched and designed by section analysis method. This section analysis design method can avoid a large amount of simulation calculation taking lots of time which is in common use for front side rail design currently. The structure designed by this method has high efficiency of material using. The estimate of the structure matches the CAE simulation result fairly.
