| 摘 要： | 采用显示动力学有限元软件LS-DYNA,结合生产实际,对H型钢万能轧制进行了仿真计算.在仿真结果的基础上,根据轧制平面内的节点位移矢量分布情况,分析了轧件断面内金属流动规律.仿真结果显示轧件断面内在立辊和平辊压下方向上存在"零位移线",说明在H型钢万能轧制过程中,在立辊和平辊压下方向上轧件内金属流动存在"位移中性面",并伴有翼缘端部金属流动产生"内翻"的情况.

| Abstract: | The dynamic explicit finite element software LS-DYNA was used to numerically simulate H-beam rolling by a universal mill.The metal flow pattern in a workpiece was studied with the simulation results of node displacement in the rolling plane.It is shown that there are zero displacement lines in the workpiece in the horizontal and vertical rollers' depress direction,which indicate that there is a neutral flow plane of displacement,in company with metal inversion phenomenon at the flange's end. |
