摘　　要：针对H型钢X-H方法生产过程,采用有限元分析软件ANSYS/LS-DYNA,建立仿真模型,完成了H型钢三机架往复连轧过程。详细描述了计算模型的建立、边界加载以及材料的定义。在模拟结果的基础上,深入分析了稳定轧制阶段轧件断面金属的流动情况、变形规律以及轧制力的特点,得到了金属沿着H型钢轧槽表面往内流动、出现冲击载荷等结论。可为H型钢的多机架往复的连轧仿真分析,以及X-H轧制工艺研究提供数值参考。With the help of ANSYS/LS-DYNA, a simulation of process of H-Beam three-stand reciprocating continuous rolling models, definition of boundary loading and materials. Based on H-Beam production process is built with the X-H method and the is completed. The paper elaborates the building of computing the simulation result, the paper also discusses the flow and deformation patterns of workpiece metal in the stable rolling phase and characteristics of the rolling force. Finally, conclusions inclusive of the faets that the metal will flow inward along the surface of H-Beam groove, impact load appears will be reached. The paper can be served as a theoretical reference for the simulation analysis of H-Beam multiple stands continuous rolling and research on rolling mill practice with the X-H method.
