摘要：

金属板料弯曲中，回弹预测与控制是产品精确成形的关键。针对厚度为0.55 mm的SUS430不锈钢自由曲面弯曲回弹问题，采用Hill48、Barlat89和YLD2000-2d 3种典型的各向异性屈服准则对SUS430不锈钢板材自由曲面弯曲成形进行有限元模拟，并结合试验验证，研究了不同屈服准则对自由曲面弯曲成形回弹量的影响规律。结果表明：YLD2000-2d屈服准则的模拟结果与试验结果吻合最好，适用于SUS430不锈钢自由曲面弯曲成形的有限元模拟；Barlat89屈服准则的模拟结果与试验结果存在一定的偏差； Hill48屈服准则的模拟结果与试验结果差异最大。在选用YLD2000-2d屈服准则的基础上，研究了冲压速度与摩擦因数两种工艺参数对自由曲面弯曲成形回弹量的影响规律。在合理的工艺参数范围内，冲压速度越大，数值模拟预测的回弹量越小。

In sheet metal bending, springback prediction and control are the key to accurate forming of product. Therefore, for the bending springback problem of free-form surface for SUS430 stainless steel with the thickness of 0.55 mm, the finite element simulation of free-form surface bending for SUS430 stainless steel sheet was carried out by three typical anisotropic yield criteria，such as Hill48, Barlat89 and YLD2000-2d, and combined with experimental verification, the influence laws of different yield criteria on springback amount of free-form surface bending were studied. The results show that the agreement between the simulation results of YLD2000-2d yield criterion and the experimental results is the best, which is suitable for the finite element simulation of free-form surface bending for SUS430 stainless steel. Furthermore, there is a certain deviation between the simulation results of Barlatt89 yield criterion and the experimental results, while the difference between the simulation results of Hill48 yield criterion and the experimental results is the biggest. Based on the selection of the YLD2000-2d yield criterion, the influence laws of the two process parameters of stamping speed and friction coefficient on the springback amount of free-form surface bending was analyzed. Within the range of reasonable process parameters, the higher the stamping speed is, the smaller the springback predicted by the numerical simulation is.
