为了解决板料成形过程中的回弹问题，选择了CAA V5开发方法中的交互模式并利用CATIA的交互式开发方式开发出了回弹补偿模块，用以完成液压橡皮囊“一步法”成形型面补偿系统开发。提出了曲线法平面截取补偿算法，将待补偿的曲面离散成若干条截取线；针对弯曲圆角弧线和弯曲面交线在法平面内进行回弹补偿操作；利用CATIA的曲面造型功能将回弹补偿后的曲线形成补偿后成形型面。利用橡皮囊成形试验中镰刀型试验件的补偿模具的成形件的精度与检验模具对比，来证明该补偿模块的可靠性。通过回弹补偿系统对成形型面进行回弹补偿操作，可以将补偿后的成形型面用于补偿模具的设计中。结果表明，基于该补偿算法可以对原始模具做出合理补偿，为补偿模具的设计工作提供设计性建议。

In order to solve the springback problem after the sheet forming process, the springback compensation module was developed by the interactive mode of CAA V5 development method and the interactive development mode of CATIA, and the development of one step shaping compensation system for rubber bladder was conducted. Then, the plane interception compensation algorithm was put forward, and the surface to be compensated was discreted as several interception lines. Next, the intersection line of bending fillet line and bending surface in normal plane was compensated for springback, and the curve after springback compensation was formed as the post-compensation surface by the surface modeling function of CATIA. Furthermore, the reliability of the compensation module was proved by comparing the precision of the sickle shaped forming parts produced by the compensation die with the test die in the rubber bladder forming tests. Thus, the springback of forming surface could be compensated by springback compensation system, and the compensated forming surface could be used to design compensation die. The results show that based on the compensation algorithm, the original die can be compensated reasonably, and a design proposal for the design of compensating die can be provided.
