摘　　要：研究钣金件的成形质量及其影响因素,对于提高飞机的整体安全性能具有重要意义。文章通过正交实验对比,找到最优的工艺参数组合,实现钣金件成形的优化。研究结果表明,在板料的冲压成形过程中,摩擦系数和压边力的增加会导致板料的最大厚薄率增大,冲压速度对最大变薄率的影响较小。在回弹过程中,压边力、摩擦系数、间隙和冲压速度的增大则会使回弹量逐渐减小。Studying the forming quality of sheet metal parts and its influencing factors is of great significance for improving the overall safety performance of aircraft.Through orthogonal experimental comparison,the article finds the optimal process parameter combination to achieve optimization of sheet metal forming.The research results show that in the stamping process of sheet metal,the increase of friction coefficient and blank holder force will lead to an increase in the maximum thickness ratio of the sheet metal,while the impact of stamping speed on the maximum thinning ratio is relatively small.During the rebound process,the increase in blank holding force,friction coefficient,clearance,and stamping speed will gradually reduce the rebound amount.
