摘要：

回弹是板料成形中不可避免的现象，有效减小回弹量是制造合格零件的保证。利用软件Dynaform对汽车车门玻璃导轨的成形过程和回弹进行了数值模拟，并对回弹产生的原因进行了合理的分析。对于零件中回弹量较大的位置，利用节点对称的方法对模具型面进行了针对性的补偿，并利用Dynaform对零件的成形质量进行了有效验证。回弹量由0.67 mm降到0.3 mm 以下，降低了近60%，模拟结果表明此方法可以有效控制回弹。

Springback is inevitable in sheet metal forming, and to effectively decrease the springback is the guarantee of a qualified part manufacturing. The forming process and springback of glass guide of car door were simulated by Dynaform software, and the causes of the springback were analyzed reasonably. At the position of the large springback produced, die surface compensation was made by the method of node symmetry, and the forming quality of the part was verified effectively by Dynaform. The value of springback was reduced from 0.67 mm to less than 0.3 mm, namely decreased near 60%. In conclusion, simulation results show that the springback can be controlled effectively by this method.
