Optimization of forging processes and die of 6082 aluminum alloy control arm using finite element simulations

In this study, the typical parts of a certain type of automobile aluminum alloy control arm were taken as the research object to address the low product quality of forged control arms. Forge’s finite element analysis and calculation software were combined to optimize the process plan and mold structure, and then trial production was conducted. The macroanalysis and mechanical performance test of the trial production samples showed that after optimizing the process plan and the mold structure, the forging developed good filling properties and exhibited no folding and shrinkage defects. In addition, the heat-treated sample obtained a uniform structure and fine grains.
