摘要：

为准确预测超高强钢预缺口产品在辊压成形中的回弹现象，通过模拟和实验相结合的方法，讨论了预中孔对辊压成形中超高强度钢板回弹的影响。建立了预开槽汽车门槛件的有限元模型，并通过连续辊压实验验证了其精度。采用超高强钢MS1300的拉伸实验确定的可变弹性模量的数学模型构建了有限元模型，发现使用可变弹性模量可以将孔区域的回弹预测精度提高15%。设计了几种成形方案，以研究不同特征对孔区回弹的影响。结果表明：预伸孔的存在降低了回弹，且在汽车门槛的不同位置，效果不同。随着机架数量、板带厚度和孔径的增加，机架间距和孔间距的减小，预冲孔所在位置的回弹减小。通过研究希望能减少辊压实际生产中孔对回弹的影响，提高预切断面的成形精度。

In order to accurately predict the springback phenomenon of ultra-high strength steel (UHSS) pre-notched products in roll forming, the influence of pre-punched hole on the springback of ultra-high strength steel sheet in roll forming was discussed by simulation and experiments. Then, the finite element model of pre-slotted automobile threshold was established, and its accuracy was verified by continuous roll forming experiments. Furthermore, the mathematical model of variable elastic modulus determined by the tensile test of ultra-high strength steel MS1300 was applied to establish the finite element model, and it was found that using the variable elastic modulus could improve the springback prediction accuracy in the hole area by 15%. Finally, several forming schemes were designed to study the influences of different features on the springback in the hole area. The results indicate that the presence of pre-punched hole reduces the springback, and the effect varies at different locations on the automobile threshold. With the increasing of the number of racks, the thickness of strip and the diameter of holes, and the decreasing of the spacing between racks and the spacing between holes, the springback at the position of pre-punched holes decreases. Thus, it is hoped that the impact of hole on the springback in the actual production of roll forming is reduced, and the forming accuracy of pre-cut section is improved.
