摘要：

针对某6XXX铝合金汽车座椅横梁，采用Autoform成形模拟软件建立热成形工艺有限元模型，进行成形工艺和零件回弹的分析研究。首先，利用Autoform进行回弹分析，通过直接补偿法对零件进行回弹补偿，多次迭代补偿后将零件的法向回弹量控制在±0.5 mm范围内，使得零件满足热成形生产要求。然后，进行模具研发和零件试制，对试制零件进行偏差检测，零件各点的总偏差均低于0.6 mm，符合主机厂的质量要求，证明了热成形模拟的合理性和有效性。模拟及零件试制结果表明，依据热成形模拟和回弹补偿结果进行零件加工能够获得优质的产品，能够为汽车高强铝合金零件的批量化生产提供设计参考。

For a certain 6XXX aluminum alloy automobile seat beam, the finite element model of hot forming process was established by forming simulation software Autoform, and the forming process and the part springback were analyzed and researched. Firstly, the springback analysis was performed by Autoform, and the part springback was compensated by the direct compensation method. After multiple iterations of compensation, the normal springback amount of part was controlled within ±0.5 mm, so that the part could meet the requirements of hot forming production. Then, the research and development of die and the trial production of part were carried out, and the deviation detection of trial production parts was conducted. The total deviation for each point of the parts was less than 0.6 mm, which met the quality requirements of the original equipment manufacture and proved the rationality and validity of the hot forming simulation. The results of simulation and trial production of parts show that the part processing based on the results of hot forming simulation and springback compensation can obtain high-quality products, which provides guidance for the mass production of automotive high-strength aluminum alloy parts.
