为解决锻造铝合金控制臂的产品质量低、试验优化周期长等问题，以某型号汽车铝合金控制臂典型零件为研究对象，采用逆向工程手段优化终锻件的结构设计，结合Forge有限元分析计算软件进一步优化工艺方案及模具结构，并进行试生产验证。试生产结果表明：优化工艺方案及模具结构后，锻件填充性良好，无折叠和缩孔缺陷，材料利用率提高了11%。对试生产样件进行宏观分析及力学性能测试，分析结果表明：热处理后试样的组织均匀、晶粒细小、力学性能明显提高。前述基于有限元模拟和逆向工程结合的锻造工艺与模具结构优化方法，能够有效地提高产品合格率、材料利用率，缩短试验周期，降低生产成本，为此类零件锻造工艺的制定提供了重要参考。

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.
