本文以翼子板鸟嘴为研究对象，通过建立数据模型，结合冲压成形CAE仿真分析技术及结构有限元分析技术，探索了不同鸟嘴结构参数对冲压工序内容排布、冲压模具强度、冲压成形性以及冲压回弹的影响。探究出满足冲压工艺需求的翼子板鸟嘴结构参数组合，为我司翼子板的前期结构设计以及后续的冲压同步工程数据校核和冲压工艺规划提供了参考依据，提高了设计效率以及数据校核的准确性和时效性，规避了工艺设计和模具开发阶段的重大风险。

Taking fender beak as the research object, this paper explores the influence of different beak structural parameters on the content arrangement of stamping process, stamping die strength,formability and springback by establishing data model and combining with stamping forming CAE simulation analysis technology and structural finite element analysis technology. The combination of fender beak structural parameters that meet the stamping process requirements is explored, which provides a reference for the preliminary structural design of the fender and the subsequent stamping synchronous engineering data verification and stamping process planning,improves the design efficiency and the accuracy and timeliness of data verification, and avoids the major risks in the process design and die development.
