摘　　要：采用有限元数值模拟技术,对轿车结构零件的拉延成形过程进行了模拟分析。对影响拉延成形质量的工艺参数进行了优化,着重优化了板料的形状和零件形面。通过对FLD图和成形结果的分析,得到了板料的形状和零件形面。最终将优化后的模拟结果与实际生产出来的拉延件结果进行了对比,验证了数值模拟的有效性。Based on finite element, the drawing formation process of an auto structure part was analyzed. The process parameters influencing the forming quality were optimized. The emphasis of the optimization was the blank shape and part surface. The blank shape and surface of part were determined after analyzing the FLD diagram and the forming result. Finally by comparing the simulation results after optimization with the experiment results, the validity of numerical simulation was validated.
