采用大变形刚粘塑性有限元法．成功地模拟了圆板料向轴对称锥形凹模内超塑约束胀形时，胀形件贴模过程。提出了简便摩擦处理方法．给出了保证计算过程稳定性的处理方法。
The use of large deformation just viscoplastic finite element method. Successfully simulating the circular plate to the axisymmetric cone-shaped concave superconducting constrained plastic deformation of the bulge, the mold-affixed process. A simple friction method is proposed. The method to ensure the stability of calculation process is given.
