Based on the forging process of 6082 aluminum alloy, and in order to meet the product performance and use requirements of the support arm for automobile air suspension shock absorber, three different forging processes were comprehensively compared and analyzed, and the optimal process was selected. Then, the workpiece with excellent internal structure and surface quality was obtained by setting the process parameters of pre-forging and final forging, and the rationality of the production process was verified theoretically by numerical simulation. Furthermore, the workpieces of different batches were tested and analyzed by random sampling, the depth of the inner coarse ring was observed, and the material parameters such as tensile strength, yield strength and elongation were obtained which were comparied with the product requirements to ensure the reliability of product quality. Through the discussion of the actual process optimization, numerical simulation and material property testing,the important reference for the research,development and production of similar products is provided.
