Abstract
The forming and springback of sail surface during the multi-point forming under force-displacement separated control (MPF-FD) was studied. Numerical simulation method was adopted to study the springback of sail surfaces with different radius, sheet thicknesses and forming forces. The results show that the springbacks on two directions influence each other. The springback on the bigger radius direction is on the leading role, and will influence that on the smaller direction. On the direction of the bigger radius, the springback is decreased with the increase of sheet thickness, forming force and decrease of the radius. On the direction of the smaller radius, the springback is decreased with the decrease of the sheet thickness and the increase of the forming force, and the radius has a small impact on springback.
