| 摘 要： | 提出了一神在板坯外缘上打工艺孔再进行拉深的新的工艺方法，分析了带孔板坯拉深的力学特征，阐明了这种工艺能提高板坯成形性能的技术关键。以带法兰的矩形盒拉深为研究对象，运用ANSYS/LS-DYNA软件建立4个有限元模型(FEM)，采用SHELL 163单元和Belystchko-Wong-Chiang算法进行有限元模拟并对其结果进行比较。结果表明：这一新工艺的拉深成形的效果十分理想。

| Abstract: | The new technique to improve forming property of sheet metal by a big margin was put forward.Mechanical characteristics of blank with holes during deep drawing were deeply analyzed,and the technical key to improve forming property of sheet metal was proposed.Taking rectangular box with flange as example,the four finite element models(FEM) were established by ANSYS/LS-DYNA software,the finite element simulations were performed by SHELL 163 element and Belystchko-Wong-Chiang algorithm,simulated results were c... |
