摘要：

为改善局部回弹补偿法的不足提出了一种解决方案。针对翼子板下部轮廓偏移问题分析了零件的回弹规律，认为局部回弹补偿法存在局限性的根本原因是其无法对型面从拱变平坦的回弹趋势进行整体准确补偿。提出了采用全型面回弹补偿的方法，基于其逆向求解原理分析得到了实现该方法的关键点，包括确保工艺本身回弹尽量小、保证求解稳健性、剔除约束噪声以及保证外覆盖件表面质量与截面线长的一致性。给出了该方法的实现步骤并应用于某翼子板，首个全工序零件的尺寸测量结果显示，A面的偏差在0.3 mm内，轮廓偏移在0.2 mm内，表明采用本方法可得到满足尺寸公差要求的零件。

A solution was proposed to improve the shortcomings of the local springback compensation method, and for the offset problem of the lower profile for fender, the springback law of part was analyzed, and the fundamental reason for the limitations of the local springback compensation method was that the springback trend of surfaces from arch to flat could not be compensated integraly and accurately. Then, the method of full surface springback compensation was proposed, and the key points for implementing this method was obtained based on the analysis of its reverse solution principle, including minimizing the springback of the process, ensuring the robustness of the solution, eliminating the constraint noise and ensuring the consistency of surface quality and cross-section line leght for outer panel. Furthermore, the implementation steps of this method was provided and applied to a certain fender. The dimensional measurement results of the first full-process part show that the deviation of A-surface is within 0.3 mm, and the profile offset is within 0.2 mm, indicating that the parts that meet the dimensional tolerance requirements can be obtained using this method.
