中文摘要:
      目的 分析汽车前围横梁连接板的冲压成形过程。 方法 以板料成形非线性分析软件 AUTOFORM 为平台,对汽车前围横梁连接板的冲压成形过程进行 CAE 分析。 根据模拟结果( 成形极限图、材料流动分布及材料变薄率) ,对拉延型面及工艺参数进行了优化。 结果 所得零件材料最大减薄率为 14 . 6% ,在 B340 LA( t = 1 . 0 mm) 材质减薄率安全范围内( 16 . 9% ) ,零件型面球化处角部无暗伤及拉裂,翻边处材料流动均匀,无开裂风险,成形结果得到大大改善。 结论 CAE 仿真能够预测零件成形过程中存在的缺陷,优化工艺参数,指导模具设计工作。 最后将优化结果用于指导实际生产,得到了符合质量要求的零件。
英文摘要:
      Objective To analyze the stamping forming process of an front beam connecting part. Methods The stamping forming process of an front beam connecting part was numerically simulated based on blank stamping non-linear finite element software AUTOFORM. According to the simulation results ( the forming limit diagram, flow distribution and material thinning rate) , the drawing surface and the process parameters were modified and optimized. Results Ultimately, the part material maximum thinning rate was 14. 6% , within the range of B340LA ( t = 1. 0 mm ) material thinning rate ( 16. 9% ) . Part surface ball and flange corners were free of cracking risk, and the defect in the forming process was eliminated. Conclusion Simulation could predict the defects of parts forming process, and help to optimize process parameters,and guide die design. Application of the optimized results to practical production resulted in eligible drawing parts.
