摘　　要：为改善金属材料屈服强度及工艺参数,控制金属材料高压成形的回弹量。本文基于Autoform有限元模拟软件,仿真分析了金属材料高成形在不同的材料屈服强度、低压压力和高压压力下,各参数对于回弹的影响,并通过样件试制验证分析结果,结果发现,金属材料屈服强度与回弹量呈正相关。低压压力值与回弹量呈正相关。高压压力值与回弹量呈负相关。To improve the yield strength and process parameters, the rebound volume of metal material is controlled.Based on Autoform finite element simulation software, the influence of various parameters on the rebound under different yield strength, low pressure and high pressure, and the yield strength of the metal material.The low pressure pressure value is positively correlated with the rebound volume.The high pressure pressure value is negatively correlated with the rebound volume.
