介绍了基于刚一粘塑性有限元方法的正向和逆向模拟技术，并将该技术应用于链轨节锻件的复杂锻造工艺的预成形设计，实现了从理想形状的终锻件设计预成形件和预成形模具的目标。所设计的预成形件和预成形模具降低了终锻模具的磨损，提高了材料的利用率，保障了预成形件在后续模具中的定位稳定性，井应用于生产实际，取得了较好的经济效益。
The forward and reverse simulation technology based on just a viscoplastic finite element method is introduced and applied to the preforming design of the complex forging process of the chain link orbital forgings. The goal of preforming molds. The designed preform and preform mold reduce the wear of the final forging die, improve the material utilization rate, ensure the prestress positioning stability in the subsequent mold, apply well to the actual production, and get better Economic benefits.
