| 目的 研究造型相对复杂的前地板纵梁高强钢(HSS)应用回弹变形特点，探寻回弹控制方法。方法 借助CAE分析技术，对零件进行全工序和回弹仿真分析，深入探讨零件回弹特点，提出回弹整改控制措施。结果 通过整改措施的落实，样件尺寸精度达到1 mm控制要求，零件平均合格率达到90%以上，满足质量要求。结论 数值仿真分析可以对零件的成形性及回弹进行预测，为工艺设计及模具开发提供有益参考。提出的回控制技术可用于指导同类型高强钢零件的模具开发工作。 |
| 英文摘要: |
| The paper aims to study the springback deformation characteristics of a complex side rail under front floor made from High Strength Steel (HSS) and seek measures for springback control. CAE analysis technology was employed to simulate whole forming processes and predict springback. Springback features and influence factors were discussed. Several springback control measures were proposed. By application of springback control measures, the size accuracy of specimen reached the quality requirement of 1mm. The average qualified rate reached 90%. The requirement on quality of sample product was met. Numerical simulation analysis can predict formability and springback of parts and provide useful reference to process design and mold development. Springback control measures proposed in this paper can be used to guide mold development of other similar parts. |
