| Abstract: | The new technology of the dieless hydroforming of spherical vessels from combination frustum shells is put forward in the present paper,and on the basis of many investigation experiments, a closed shell with a proper structure is determined,and its hydrobulging process is simulated by means of elastoplastic finite element method,at last success is obtained through experiments. |
