摘　　要：主要论述了大型突变截面连杆制坯辊锻的关键工艺。以刚塑性有限元法为基础,利用Deform-3D软件,对其进行了三维有限元模拟。揭示了连杆制坯辊锻变形过程中金属的流动规律,分析了辊锻成形过程中各道次辊压坯料各部位应变的分布情况,以及各道次辊锻过程中模具受载情况,从而为连杆辊锻制坯工艺及模具设计提供可靠的理论依据。The key roll forging process of connecting rod blank with large and different sections was explained. Based on rigidity-plasticity finite element, the process was simulated by Deform-3D software. The behavior of metallic flow was discussed. Distribution of strain and die load of each time in blank roll forging process were analyzed. The results provide dependable theory foundation for process and die design of roll forging making blanks.
