| Abstract: | To optimize the process parameters of the first pass spinning of large-sized complicated thin-walled shell,based on the platform of ABAQUS,a solid finite element(FE) model has been established;the field outputs related to solid element model,including the wall thickness and the fittability,have been achieved by the second-develop;and the effects of blank diameter and the interaction between deforming area and other areas on the power spinning of the large-sized cone has been investigated.By using the orthog... |
