Typical parts for a certain type of automobile aluminum alloy control arm were taken as the research object to solve the problems of low product quality and long test optimization cycle of forged aluminum alloy control arm. Reverse engineering mean was used to optimize the structure design of final forgings, combined with Forge finite element analysis and calculation software, the process plan and die structure were further optimized, and the trial production verification was finally conducted. The results of the trial production show that the forgings are well filled without folding and shrinkage defects, and the material utilization rate is increased by 11% after optimizing the process plan and die structure. Macro-analysis and mechanical performance tests were conducted on the trial production samples. The analysis results show that the samples have a uniform structure, fine grains and significantly improved mechanical properties after heat treatment. The aforementioned method based on the combination of finite element simulation and reverse engineering to optimize the forging process and die structure can effectively improve the product qualification rate and material utilization rate, shorten the test cycle, and reduce the production costs, which provide an important reference for the formulation of forging process for such parts.
