Abstract：

The influences of die clearance, velocity, bending radius and thickness of material on forming height of cushion segment were investigated through orthogonal experiment based on numerical simulation by the software DYNAFORM, and the order of factors was die clearance, bending radius, thickness of material and velocity respectively by visual analysis of orthogonal experiment. Additionally, the optimized forming plan of cushion segment was acquired by orthogonal experiment. They were the die clearance 1.0t, velocity 5000 mm·s-1, bending radius 24.3 mm and thickness of material 0.8 mm. The values of simulation and experiment after optimized experiment are 2.94 and 2.62 mm respectively, and their error is about 12.21%.
