| 摘 要： | A proposal for two types of press close to die,including blank coming in die and Blank cov-ering die,and four criteria for formability is put forward in the study of the superplastic airbulge forming of the metallic thin wall components.A dimensionless weigh mathematic modelfor the criteria of superplastic air bulge forming is developed to be:Q_w=1.56(WS)/(HF)+2.37(0-π/(180)-r/(r_0)+0.19The superior formability of components is approaching,if Q_W≥1,and the worse,if Q_W<1.Itwas confirmed by practice that the above mentioned model is accurate sufficiently.

| Abstract: | A proposal for two types of press close to die,including blank coming in die and Blank cov- ering die,and four criteria for formability is put forward in the study of the superplastic air bulge forming of the metallic thin wall components.A dimensionless weigh mathematic model for the criteria of superplastic air bulge forming is developed to be: Q_w=1.56(WS)/(HF)+2.37(0-(?)π/(180)-r/(r_0)+0.19 The superior formability of components is approaching,if Q_W≥1,and the worse,if Q_W<1.It was confirmed by practice that the above mentioned model is accurate sufficiently. |
