摘要
介绍了板料成形过程中的回弹模型,包括解析模型、材料模型、单元模型、摩擦模型和算法模型,分析了回弹的影响因素,从控制工艺参数和模具零件型面补偿法2个方面分析补偿回弹的措施,并对回弹问题的研究前景作了展望。
The springback model of sheet forming was introduced including analytical model, material model, unit model, frictional model and algorithm model. The influence factors of springback and the measures for compensating springback were analyzed from two aspects that the die shape control and die parts' profile compensating.
