| Abstract: | Viscous pressure forming (VPF) is a new developed sheet metal soft-punch forming process in 1990s. The basic principle and characteristics of VPF are described. Influences of viscous medium's properties on sheet deformation are analyzed by finite element method. The forming of nickel-based superalloy corrugated thin-walled part with small radius, aluminum alloy ladder part and local inner-pressure expanding and outer-pressure sinking axisymmetricrcurved sheet parts by VPF are presented and analyzed. |
