摘　　要：分析现有金属板料拉深回弹产生的机理中,对影响板料成形回弹的多个因素如材料的机械性能、凹模圆角半径R、压边力F等进行了解析,并对回弹补偿进行了研究。以某风机叶片为应用实例,研究了该风机叶片成形后回弹分布的规律,并采用了多步隐式算法对其进行了回弹补偿,最终达到工件精确成形的目的。During the study on the mechanism of the existing metal sheet drawing springback,the factors infecting sheet＇s springback were analyzed,such as ：materials machnical properties ,die profile radius R,pressure-pad-force F etc. The springback compensating was research. This was applied for a fan blade. The spring back＇s law was found after the forming of springback and compensation was adopted with a multi-step implicit algorithm. So the precision forming can be easily realized.
