基于 产品原始数模、FEM软件进行回弹分析以后的数据位置，Compensator（回弹补偿）就可以自动创建经过补偿的数模，相邻面的连续性还得到了保留。不但缩短了创建补偿数模的时间，而且数模质量也得到了很大的提升。

实验证明，利用该模型可以有效地完成对模具形状修正，实现了复杂冲压件的回弹补偿。
The experiments show that the system can completion the amendment of the mold of the shape effectively and realized the springback compensation to the complex stamping.
由于零件厚度薄、多向弯曲、回弹量大且相互影响，用常规回弹补偿法很难确定回弹规律。
Since the part is thin, multi-direction bending and springback is large, it is very difficult to decide the springback law using the usual compensation method.
最后，研究了回弹的原因和介绍了使用JSTAMP对车身底座横梁板执行回弹补偿的过程。
Lastly, a research for springback reason and a compensation for tool surface of underbody cross member panel were performed using JSTAMP.
