| Abstract: | Hydraumatic and spontaneous bulging of bimetal tube in the case of tube end immovable and tube end unrestricted was studied by utilizing numerical simulation technology. The critical hydraumatic bulging force and the deformation nile of bulging height, tube length and thickness under these two conditions were acquired. It was found that the numerical simulation technology plays and important role in the study of bulging technology of metal multiunit tube. |
