摘要
基于Pam-stamp 2G有限元分析软件,模拟了某汽车B柱的冲压成形过程,采用冷轧连续退火DC03和DC04钢板对该零件的成形适应性进行了分析.结果表明,DC04相比DC03有更高安全裕度,可以满足成形的需要.模拟了压边力为1 800 kN和2 500 kN时DC04材料的成形情况,发现当压边力为2 500 kN时,能够有效地降低零件的起皱程度.
Based on finite element analysis software Pam-stamp 2G, stamping process of automobile B-pillar is simulated. The stamping adaptability of cold rolled continuous annealing product DC03 and DC04 is studied. The result indicates that DC04 has higher safety margin than DC03 and it can fit for forming of component. In addition, stamping process of DC04 with pressure pad force 1800KN and 2500KN is simulated. It is found that the degree of wrinkling can be brought down when pressure pad force is 2500KN.
