| 摘 要： | 等边双圆锥台壳体在内压的作用下,赤道环焊缝处易产生失稳起皱,且胀形后所得容器圆度较差。针对这一问题,对其胀形过程进行了有限元数值模拟,并通过改变圆锥台的初始形状,来保证容器的圆度和避免赤道处的失稳起皱。

| Abstract: | Under internal pressure, equilateral frustum shell tends to wrinkle at the equator, and the circular degree of the obtained vessel is poor. Pointing to this problem, a numerical simulation was firstly carried out, and then some measures was taken to prevent the equator from wrinkling by slightly changing the shape of the frustum shell, as a result, the bulged vessel became more round. |
