Finite element analysis of metal flow during H-beam rolling by a universal mill

摘要: 采用顯示動力學有限元軟件LS-DYNA,結合生產實際,對H型鋼萬能軋制進行了仿真計算.在仿真結果的基礎上,根據軋制平面內的節點位移矢量分布情況,分析了軋件斷面內金屬流動規律.仿真結果顯示軋件斷面內在立輥和平輥壓下方向上存在"零位移線",說明在H型鋼萬能軋制過程中,在立輥和平輥壓下方向上軋件內金屬流動存在"位移中性面",并伴有翼緣端部金屬流動產生"內翻"的情況.Abstract: The dynamic explicit finite dement 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.
