摘要:
 针对复杂结构零件冲压成形时出现的破裂与拉延不充足等问题,采用板料成形模拟软
件Dynaform 对汽车前翼子板充液拉深工艺进行了有限元数值模拟研究。依据翼子板各处进料规
律,提出了三种拉延阻力系数不同的拉延方案。以零件的成形极限图( FLD) 为分析标准,研究了拉
延阻力系数、液室压力加载路径和压边力对翼子板成形质量的影响规律。研究结果表明: 设置合理
的拉延筋、加载路径和压边力,可以改善翼子板的成形性能,并且能够获得壁厚分布均匀的零件。
Abstract:
 Aiming at the problem of failure and insufficient drawing when stamping forming for complex
structure parts,we conduct numerical simulation of hydromechanical deep drawing to automobile front fender.
According to the feeding law of fender,we propose three different drawing resistance coefficient programs,study the
influence rules of main forming parameters on fender forming quality,like drawing resistance coefficient,chamber
pressure,loading path,blank holder force,with the standard of forming limit diagram. The results show that under
the reasonable match of drawbeads,loading path and blank holder force,forming performance of fender could be
ameliorate,and obtain the part with uniform wall thickness distribution.
