中文摘要：基于金属轧制过程中体积不变原则，采用DEFORM有限元软件，对多种坯料形状轧制成形高颈法兰进行有限元数值仿真，分析坯料形状对轧制成形高颈法兰的影响规律，给出轧制成形方法成形高颈法兰坯料的合适坯料形状。研究结果为实现和推广高颈法兰轧制成形技术奠定了理论基础。
英文摘要：Based on the principle of volume constancy during rolling process, using DEFORM FEM software, the forming processes of long neck flange with different blank shapes were simulated. The influence rules of blank shape on roll forming of long neck flange were analyzed. Through this study, the right blank shape for forming long neck flange was obtained. The research conclusions can provide scientific basis for forming long neck flange.
