摘　　要：利用有限元分析软件ANSYS/LS-DYNA,对三辊行星轧机轧制过程进行了有限元分析。介绍了有限元模型的建立、约束的定义和载荷的施加。根据模拟仿真结果,对轧件的应力和应变分布、轧制负荷以及轧件速度进行了分析。The analysis of three- roll planetary mill rolling process has been conducted by finite element method with software ANSYS/LS - DYNA. The paper introduces the creation of the finite element model, the definition of constraints and the exertion of loads. Based on the simulation results of workpiece＇s deformation, the stress and strain distribution of work - piece, the rolling force and work-piece rolling speed are studied.
