本文在研究金属薄壳构件超塑气胀成形时,提出两种贴模方式(内填模型和外包模型)与四个判据的关系。同时建立一超塑气胀可成形性判据数学模型: Q_w=1.56(WS)/(HF)+2.37(θ-φ)π/(180)-r/r_0+0.19 Q_W≥1者可成形性好,Q_W<1者可成形性差。试验证明,上式判定构件可成形性有较高的准确性。

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.
