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。这些结果对制定圆柱体镦粗时参数的设定有指导意义。The paper uses the software ANSYS/LS-DYNA to build the 3D finite element model of the cyhnder upsetting and to analyze the internal strain distribution under the different upsetting deformation. At the same time, the finite element analysis is compared with the corresponding theoretical result. When the cylinder has the more plastic deformation, the two results are fit very well. The results provide the reference for the estabhshment of the cylinder upsetting process parameters.
