摘要:
在多款车型实践基础上,总结了一种提升汽车覆盖件材料利用率的方法,给出了工作流程图,即在同步设计开发或油泥车阶段,应用板料成形CAE模拟手段,通过优化零件边界、工艺补充面、坯料形状的交互试错,获得了优化的零件状态和合理的工艺方案,实现了材料利用率的最优化;以B车型的轮罩外板零件为实例,采用上述方法可将该零件的材料利用率从38.04%提升到56.67%,每台节省材料3.61 kg、实现效益22.96元,证实了该方法有效可行。

A method to improve material utilization ratio of automobile sheet metal parts was elaborated considering many kinds of automobile types, and the workflow chart was given. The CAE simulation technology of sheet metal forming was adopted during the design process. The optimized part condition and reasonable craft plan were gained by optimization of part boundary, addendum surface, blank shape executed by interactive trial and error. Consequently, the maximum optimization of material utilization ratio was realized. For the wheel house outer of B car, the material utilization ratio was improved from 38.04% to 56.67%, material was reduced up to 3.61 kg per car, and cost is saved 22.96 yuan per car. Therefore, it is concluded that the method is effective and feasible.
