摘要：

以5182铝合金汽车引擎盖内板为例，研究充液成形技术在其成形过程中的应用。根据拉伸实验结果，采用Dynaform对铝合金引擎盖内板充液成形工艺过程进行有限元仿真。通过实验验证，分析实验过程中零件成形后的缺陷形式并提出了相应的解决措施。结果表明，通过调整拉延筋高度、控制液室压力、增加零件润滑等措施，能够解决零件成形过程中的质量缺陷。优化工艺参数后的充液成形制件具有良好的贴模性及较优的表面质量，能够满足设备低吨位要求，最大减薄率小于17.2%，最终经过零件指标检测，成形零件合格。充液成形为汽车铝合金引擎盖内板的大规模生产提供了一种可靠工艺。

For 5182 aluminum alloy automobile hood inner panel, the application of hydroforming technology in its forming process was studied. Then, according to the tensile experiment results, the hydroforming process of automobile hood inner panel for aluminum alloy was simulated by Dynaform, and the defect forms of part after forming in the experiment process were analyzed, and the corresponding solution measures were proposed. The results show that the quality defects in the forming process of part can be solved by measures, such as adjusting the height of drawbead, controlling the pressure of liquid chamber and increasing the lubrication of part. The part obtained by hydroforming after optimizing the process parameters can fit the mold well and has better surface quality, which can meet the requirements of low tonnage equipment, and the maximum thinning rate is less than 17.2%. Finally, the formed part is qualified after the part index detection. Thus, the hydroforming provides a reliable process for the mass production of automotive aluminum alloy hood inner panel.
