摘　　要：采用刚塑性有限元模型对前轴辊锻3道次进行了有限元模拟,分析了辊锻过程中坯料的变化规律、等效应力分布及辊锻力矩的变化规律。模拟结果对于指导实际生产,提高模具设计水平具有重要意义。The three passes roll forging process was simulated for front axle by using the rigid-plastic finite element model. The transformation law of blank, the roll forging torque and the effective stress distribution were analyzed during the three passes roll forging process. The result of the simulation has important significance for guiding the practical production and improving the level of die design.
