圆锥台 meaning in Chinese

cone frustum
frustum cone

Under internal pressure , equilateral frustum shell tends to wrinkle at the equator , and the circular degree of the obtained vessel is poor
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。
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
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。
