摘要：

针对围圆冲压成形中易发生卡箍折裂的现象，使用SolidWorks建模，利用ABAQUS进行仿真运算，分析不同冲压速度下，卡箍箍带弯曲成形后的应力、应变、厚度的分布情况。结果表明：在不同冲压速度下，卡箍箍带的应力、应变以及厚度的变化趋势大致相同，均在耳圆部分和最底部出现拉应力增大、应变集中以及厚度减小的现象，表明在此3处出现变形较大的现象；经过对不同冲压速度下的卡箍箍带进行模拟仿真，得出在100 mm·s-1的冲压速度下，卡箍箍带的应力、应变以及厚度的变化分布均相对均匀，且整个箍带的变形相对平稳。

Aiming at the phenomenon that the clamp hoop was prone to crack in the process of circular stamping, the calculated model was established by SolidWorks, and the simulation calculation was conducted by ABAQUS to analyze the distribution conditions of stress, strain and thickness for clamp hoop belt after bending under different stamping speeds. The results show that under different stamping speeds, the variation trends of stress, strain and thickness of the clamp hoop belt are roughly the same, and the phenomenons of tensile stress increasing, strain concentration and thickness decreasing all appear at the ear circle and the bottom, indicating that there is a large deformation in these three places. Through the simulation of the clamp hoop belt under different stamping speeds, it is concluded that under the stamping speed of 100 mm·s-1, the distributions of stress, strain and thickness change of the clamp hoop belt all are relatively uniform, and the deformation of the whole hoop belt is relatively stable.
