摘要：

锻造中锻件的塑性变形远远大于弹性变形，因此忽略了锻件变形后的回弹问题，但随着精锻成形技术的发展，研究工件的几何精度误差以及预测回弹已成为精密锻造成形工艺中一个亟待解决的问题。本文回顾了回弹现象的研究历史，从解析法、测量实验、数值模拟3个方面综合论述国内外精锻成形回弹现象的研究现状、存在的问题以及所取得的成果，对精锻成形回弹现象的研究有着重要的参考价值与指导意义。

The plastic deformation of forgings is greater than elastic deformation in forging, and the springback after the deformation of the forging is ignored , but as the precision forging technology development, researching on geometry precision error of workpiece and predicting springback has become a problem to be solved for the precision forging process. The research history of springback was reviewed，according to analytical method，experimental measurement and numerical simulation，the research situation,the existing problems and achievements of the springback of precision forging at home and abroad were comprehensively discussed,which had an important reference value for the research of precision forging springback .
