摘要：

精密锻件在工艺设计初期通常存在多种成形工艺方案，为确定最合适的工艺，以汽车法兰盘体零件为研究对象，应用CAE分析软件Deform-3D进行了热力耦合数值模拟。由于零件结构复杂，通过分析可知无法一次成形，结合塑性成形技术，初步确定了3种成形工艺方案。首先，从锻件的成形质量及模具使用寿命方面进行了全面的分析和比较。然后，通过建立数学评估模型从应力值、应变值、模具载荷值、零件损伤值等多方面进行优选。结果表明，方案3在锻件质量、模具使用寿命等各方面均存在优势。最后，采用方案3成形工艺进行了生产试验，获得的法兰盘体零件成形饱满，外形良好、无缺陷。通过有限元技术与数学模型的有机结合，能够高效地获得最佳工艺，大大降低试模成本。

In the early stage of process design, there are many kinds of forming process schemes for precision forgings. In order to determine the most suitable process, for automobile flange body part, the thermo-mechanical coupling numerical simulation was carried out by CAE analysis software Deform-3D. Due to the complex structure of part, it could not be formed at one time by analysis, and combined with the plastic forming technology, three forming process schemes were preliminarily determined. Firstly, the forming quality of forgings and the service life of mold were comprehensively analyzed and compared. Then, the stress value, strain value, load value of mold and damage value of part were optimized by established mathematical evaluation model. The results show that scheme 3 has advantages in forgings quality, service life of mold and other aspects. Finally, the production test was carried out by using the forming process of scheme 3, and the flange body parts were fully formed with good shape and without defects. Thus, through the organic combination of finite element technology and mathematical model, the best process could be obtained efficiently, and the cost of die test is greatly reduced.
