摘要：

基于6082铝合金锻造成形工艺，为了满足汽车空气悬挂减震器支撑臂的产品性能和使用要求，综合比较分析了3种不同的锻造工艺，选择最优的工艺流程，通过对预锻、终锻等工艺参数的设定，得到内部组织和表面质量优良的工件。通过数值模拟仿真，从理论上验证了该生产工艺流程的合理性。最后通过随机取样对不同批次的工件进行检测分析，观察内部粗晶环深度，并得到抗拉强度、屈服强度和伸长率等材料参数，与产品要求的参数进行对比，进一步确保了产品质量的可靠性。通过对实际工艺优化、数值模拟仿真以及材料性能检测3个方面的论述，为同类产品的研发和生产提供了重要参考。

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.
