| 摘 要： | 文章在研究高强度钢板成形特性、回弹特性以及拉毛特性的基础上,深入探讨了先进高强度钢板冲压过程的变形特征。研究结果表明,与传统HSLA钢板相比,DP钢和TRIP钢具有较好的应变均化能力,和较高的成形性,有利于提高零件的使用强度。钢种特性和材料参数对回弹影响显著,使先进高强度钢板尺寸精度控制难度加大。当钢板强度升高时,高强度钢板表现出更易产生拉毛的趋势。

| Abstract: | The forming characteristics of advanced high strength steel are studied in this paper based on the experimental study and simulation of formability, springback and galling. It is shown that compared to conventional HSLA steel, DP steel and TRIP steel have relatively higher ability to ensure the strain distribution much evener and obtain much higher formability, which will improve the part strengths remarkably. The steel grade and material mechanical parameters have obvious effect on the spring-back, which will increase the difficulty to control the dimension precision of high strength steel. With the increase of steel strength, the galling defects are much easier to occur. |
