摘　　要：针对某型号飞机铝合金复杂构件充液成形的失效形式,采用有限元数值模拟和试验的手段,研究了毛坯形状、液室压力等关键工艺参数对成形失效的影响,给出了铝合金复杂构件充液成形质量控制的措施,为此类型航空复杂构件的充液成形提供了技术指导。Sheet hydroforming is an advanced forming process technology. Sheet hydroforming has been developed greatly in recent years and began to applying into automobile, aircraft, appliances and other manufacturing areas. In this paper, aiming at the forming failure types of the sheet hydroforming of complicated aircraft aluminum part, effects of key process parameters including blank shape,cavity pressure etc., on the forming failure were explored by using both the finite element numerical simulation and experime...
