摘　　要：针对新一代航空制造材料玻璃纤维增强铝合金层板(GLARE),以低约束GLARE为板料制备了具有变曲率和曲面特征的异形盒形件,并采用流体辅助成形工艺进行试验,探究了压边力、液压及其加载路径对试件成形质量的影响规律,根据零件失效机理分析得到了有利于成形的最佳工艺参数,并结合优化后的液压加载路径得到复杂构件成形规律。分析了不同成形高度异形盒形件的失效形式。结果表明:在一定范围内增大压边力与液压有利于零件成形;采取较大液压加载速度并保压的路径可提高零件的成形质量。For a new generation of aerospace manufacturing material Glass Fiber Reinforced Aluminum alloy Laminates(GLARE),the irregular box-shaped parts with variable curvature and curved surface characteristics were prepared by using low-constraint GLARE as sheet metal,and the experiment was conducted by the fluid-assisted forming process to explore the influence laws of blank holding force,hydraulic pressure and its loading path on the forming quality of specimen.Furthermore,according to the failure mechanism analysis on the parts,the best process parameters for the forming were obtained,and combined with the optimized hydraulic pressure loading path,the forming law of complex components was obtained.In addition,the failure forms of irregular box-shaped parts with different forming heights were analyzed.The results show that increasing the blank holding force and hydraulic pressure within a certain range is beneficial to the forming of parts,and adopting the path of larger hydraulic pressure loading speed and holding pressure improves the forming quality of parts.
