Abstract: The selection of the A-pillar cross-sectional structure of an automobile needs to consider factors such as safety, economy, appearance, wind resistance, installation, etc. Among many factors, safety is undoubtedly the most important. This paper used simulation to study the vertical and axial collisions of four different structures of automobile A-pillar sheet metal parts at different speeds. From the displacement, contact force and energy conversion of the simulation results, the resistance of different structures to deformation was analyzed. The best structure of automobile A-pillar sheet metal parts was selected from the perspective of safety and economy. The results show that the structure 4 with transverse and longitudinal cross ribs has the strongest ability to resist deformation, while the structure 3 with only the longitudinal ribs has the best processing economy and better safety.

摘要: 汽车 A 柱截面结构的选择需要考虑安全、经济、外观、风阻、安装等因素,诸多因素 中安全是最重要的。论文以模拟仿真研究汽车 A 柱钣金件四种不同结构在不同速度下的垂直 碰撞、轴向碰撞情况,从模拟仿真结果的位移量、接触力和能量转化三方面结果分析了不同 结构抵抗变形的能力,并从安全性和经济性角度考虑选择最优汽车 A 柱钣金件结构。结果表 明,有横纵向交叉加强筋的结构 4 具有最强抵抗变形的能力,而只有纵向加强筋的结构 3 具 有最好的加工经济性和较好的安全性。
