摘要
采用基于热力耦合的刚粘塑性有限元法对汽车前轴制坯辊锻成形工艺进行了模拟,分析了三道次辊锻过程中坯料的金属流动、温度场、模具受载情况,为进一步掌握前轴精密制坯辊锻成形机理、制订合理的工艺参数提供了可靠的理论依据。
Blank-making roll forging process is simulated for automotive front axle,using a thermomechanical coupled rigid-plastic finite element method.The metal flow process,equivalent stress and strain field,temperature field and load status of rolling die are analyzed.This provides a dependable theoretical basis for understanding the deforming mechanism and selecting reasonable parameters for the precision rolling forging performing of front axle.
