摘　　要：利用有限元软件ANSYS/LS-DYNA建立了圆柱体镦粗的三维模型,分析了不同镦粗变形量下其内部的应变分布情况,并把有限元计算值与相应的理论结果进行了对比分析,当圆柱体有较大塑性变形时,二者的结果相吻合。The paper used the software ANSYS/LS-DYNA to build the 3D finite element model of the cylinder upsetting and to analyze the internal strain distribution under the different upsetting deformation. At the same time, the results gotten by the finite element analysis was compared with the corresponding theoretical results. When the cylinder had the more plastic deformation,the two results were fit very well. The results provided the reference for the establishment of the cylinder upsetting process parameters.
