摘要：

利用有限元软件Autoform模拟汽车左右侧边梁加强板的冲压成形过程和回弹，以压边力、摩擦因数、冲压速度和模具间隙为优化变量，以最大减薄率、最大回弹量为评价指标，设计正交试验，确定最优工艺参数组合为：压边力为450 kN、摩擦因数为0.13、冲压速度为1500 mm·s-1、模具间隙为1.04 mm。基于最优工艺参数模拟该制件的冲压成形和回弹，在制件减薄率降到22.7%且满足成形质量的前提下，对制件的立面和法兰面进行了反向回弹补偿设计。通过对比补偿后制件的回弹模拟结果和实际生产制件产品的检测结果可以看出，模拟结果和实际生产结果基本相符，并且制件的最终成形质量和回弹量符合技术要求，为同类制件冲压成形研究提供了有益的指导。

The stamping process and springback of left and right side beam reinforcement plates for automobile were simulated by finite element software Autoform. Then, taking blank holding force, friction factor, stamping speed and die clearance as the optimization variables, and the maximum thinning rate and the maximum springback amount as the evaluation indexes, the orthogonal test scheme was designed, and the optimal process parameters combination was determined to be the blank holding force of 450 kN, the friction factor of 0.13, the stamping speed of 1500 mm·s-1 and the die clearance of 1.04 mm. Furthermore, based on the optimal process parameters, the stamping and springback of parts were simulated, and on the premise that the thinning rate of part was reduced to 22.7% and the forming quality was met, the reverse springback compensation design was conducted on the facade and flange of part. Finally, the springback simulation results of the compensated parts and the test results of the actual production parts were compared. The results show that the simulation results are basically consistent with the actual production results, and the final stamping quality and the springback amount of parts meet the technical requirement, which provides useful guidance for the research on the stamping of similar parts.
