摘要：

为了充分应用液压成形柔性制造技术在航空钣金件制造领域的优势，从理论上深入分析板材液压拉深中板料的失稳行为与预防机制，使得该工艺在实际应用中得到广泛的推广。结合数值模拟与实验验证，研究航空工业中大量应用的复杂薄壁整体钣金件液压成形制造技术。通过对3种不同材料、不同形状的典型零件液压成形过程的数值仿真，准确预测起皱和破裂等缺陷，并获得了液室压力和合模间隙对缺陷的影响。利用工艺优化手段并结合有限元技术，讨论了3种典型零件的液压成形工艺，分析出关键的工艺参数范围，确保了利用液压成形技术制造出高质量、高精度的复杂薄壁航空整体钣金件。

In order to take full advantages of hydroforming technology in the field of aerospace sheet metal, the instability behavior and prevention of plate in the hydroforming process were analyzed theoretically, which made the hydroforming technology to be widely applied in practice. The hydroforming technology on whole complex thin-walled sheet in aviation industry was researched by combining with numerical simulation and experimental verification. The defects of wrinkle and crack etc. were predicted by simulating the hydroforming process of typical parts with three kinds of materials and shapes, and the effects of chamber pressure and holder gap on defect were gained as a result. By the method of optimization process and the finite element technology, the technologies of hydroforming process about three typical parts were discussed and the scope of key parameters were obtained, which ensured to obtain a whole complex thin-walled sheet with high quality and precision by the hydroforming technology.
