回弹是板材成形过程中不可避免的一个普遍现象,直接影响到冲压件的尺寸精度和零件最终形状。因此,回弹模拟是板材成形过程模拟中的一个关键问题,也是最为棘手的问题。本文在系统地归纳了国内外众多学者在应用有限元技术进行回弹模拟研究的基础上,对回弹模拟的历史发展、回弹模拟的计算方法、影响回弹模拟的主要因素以及回弹的预测和补偿等方面作了详尽的论述,对回弹模拟研究有着很好的参考价值与指导意义。

Springback is an inevitable and universal phenomenon in sheet metal forming,which may affect the tolerance and final shape of stampings.Therefore,springback simuhtion is a key problem in the simulation of sheet metal form- ing,and is a thorny problem too.Many simulation methods of springback reported by finite dement analysis at home and abroad were systematically reviewed,the development history,calculated method,major influence factors in spri- ngback simulation and predictions and compensations of springbaek were presented in detail,which were good refer- ences and guides for the study of springback simulation.
