| Abstract: | The stamping springback and springback compensation of the rear door outer panel was analyzed by using Autoform R7 software. Through the CAE analysis and control of the whole process, and the parameters affecting the accuracy of the springback analysis results were set. After completing three schemes of springback compensation, a scheme met the actual needs was put forward. Finally, its effectiveness was verified, and the tolerance of final product was fluctuated within the range of ±0.5 mm. |
