| 摘 要： | 针对高强度钢在汽车轻量化中应用的实际情况,通过单向拉伸试验与弯曲成型试验,对普通汽车车身覆盖件用钢与高强度钢的基本力学性能、冲压成型性能进行了对比分析,并以简单V形件为对象,结合有限元软件Dynaform进行弯曲回弹数值模拟分析。结果表明：高强度钢的塑性及成型性能比普通低碳钢差,但回弹量对弯曲角度的敏感性高于普通钢,可以通过选取合适成型角度及相应成型工艺改善高强度钢的回弹量,此外,数值模拟是一种预测材料回弹量的非常有效的技术手段。

| Abstract: | According to application of high-strength steel in auto industry,we made a comparative analysis for basic mechanical properties and press forming performance of the ordinary automobile steel and high-strength steel through tensile test and bending test.As simple V-pieces for objects,based on the bending experiments,using finite element software(Dynaform),numerical simulation of bending spring was analysed.The results showed that high-strength steel forming properties and the plastic were worse than those of... |
