摘要：

基于DYNAFORM有限元软件的数值模拟，利用正交试验研究了凸、凹模间隙，冲压速度，弯曲半径以及板料厚度4种工艺参数对波形片成形高度的影响。通过正交试验的直观分析得出各因素对波形片成形高度影响的主次顺序依次为：凸、凹模间隙，弯曲半径，板料厚度，冲压速度。此外，由正交试验得出波形片成形的最优试验方案为：凸、凹模间隙为1.0t，冲压速度为5000 mm·s-1，弯曲半径为24.3 mm以及板料厚度为0.8 mm。波形片优化后的试antong Science and Technology College, Nanjing Institute of Technology验方案模拟值与试验值分别为2.94和2.62 mm，两者的误差为12.21%。

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%.
