However, in the sheet metal forming technology, wrinkling, rupture, deformation and rebound and other quality problems are more and more prominent, which not only caused a lot of material waste, but also seriously restricted the use of aluminum alloy sheet in the automotive industry The Therefore, to explore a suitable for aluminum alloy sheet stamping of the excellent process, has become the focus of many car manufacturers.</p><p>In this paper, the finite element analysis software ANSYS Workbench is used to analyze the stamping of aluminum forming components in automobile bumper, and the main factors leading to its quality problems are found out. Combining with the analysis results, the existing stamping process is optimized reasonably, To achieve the purpose of improving the yield.</p><p>Key words &nbsp;Finite element analysis &nbsp;aluminum
