| 摘 要： | 在分析环形锻件扩孔变形的基础上，设定了运动学允许的位移增量场，利用增量方法将非稳定变形转化为稳定变形，分析计算了扩孔展宽量。理论计算与实验结果基本一致。

| Abstract: | On the basis of analyzing deformation of the circular forging expand,the permissible rinematic velocity field is suppossed,the non-steady deformation is converted into the steady deformation by means of increment method,and the spreading volume of expand process is calculated.The calculated results are in good agreement with the experimental ones. |
